OEM air filter $$??

[MTPockets]

What are you guys paying for 4.2L air filters? I just had to swap out mine to the tune of ~$24 :crazy: . (Carquest filter) I noticed when I got the TB a little over a week ago, it had lots of sand under the hood. I pulled the AF to find it PACKED with sand! I tapped it on the ground and it literally left a pile of sand :x . I pulled the whole air intake tract to inspect, but thankfully it was clean as a whistle down stream of the AF. My TB was a former fleet vehicle from Virginia, so now I *assume* it was near a beach. Gotta love that air filter 'box'. The lower half of the 'clamshell' is the washer fluid bottle, while the top half is just a big chunk of hollow plastic to absorb intake noise :undecided . Anyway.. for a chevy, that's one expensive airfilter!

Invest in the K&N. Its been worth it to me. I wonder if your TB came from where I am. I am in Virginia Beach.:cool:

[jimmyjam]

think it was under $20 at walmart

Word, return that filter and get a KN drop in!

[ghoster]

Thats 2 votes for the K&N!! :D

[bully712]

Beach Sounds good right now. Another for the K&N.

[03slt_soccal]

oe 19.99 is good i sell them for that but definitely get the k&n drop in or the cai system

Walmart will be significantly cheaper, but I vote for the K&N. Uses the E3009. Filter plus recharge kit will run you about $60 and you'll never buy an air filter again.

[rcam81]

I have a K&N filter too. I keep the old paper one in the garage so that when I need to clean the K&N, I put the paper one in. That way the K&N can be completely dry before it gets oiled.

Correction. All TrailVoys use the "E1009" filter :thumbsup:

[trailblazin02]

Just bought an autozone re-charge(non K&N) and it was only $25. :thumbsup:

[AbuAbdulAziz]

After tring the K&N for a couple a days now, i say K&n K&N K&N :D

[jay boy]

put in a k&n e 1009. Left the top cover off the w. fluid bottle. Covered the hole in the air intake. Used a nice black plastic strap across the tube ran it between the two bolt holes used for the stock cover. sounds much better! The strap is not really needed I just did it for looks. The filter is around $60.

About the time you spend another 24 or 25 bucks on another restrictive air filter, you could have bought a K&N. Your pocket would love you later as well as your vehicle running and breathing better.:)

A fool and his money saying, it's your money:raspberry

To be honest, K&N air filters spook me. I've seen first hand what they do to vehicles equipped with MAF's (I know the 4.2's are MAFless). They dirty the heck out of them, even when maintained & oiled per spec. That's WAY too much dirt carry-over for a daily driver. Plus, I've never noticed any performance or economy gains from just using a K&N. A regular OEM style filter lasts a looooooooong time with my usage so ~$24 every ~30Kmi isn't bad, it was just that initial sticker shock that got me. :x

Thanks!

Curious if the air filter replacement indicator gizmo was showing any movement with the sand-packed filter? I don't know for sure if the '05 has one. My '02 does.

I bought a Green Filter for my TB. Reusable like the K&N but comparing them the Green doesn't have holes in the filter media I can see light through like the K&N that's on my S10. Also the Green is claimed to filter smaller particles, down to 5 microns.

I have never noticed any significant difference with performance or MPG with either the K&N or the Green. Main reason I bought the Green was to complement the Borla exhaust and my cold air intake mods. Figured maybe the cumulative effect of all together would add up to something noticeable. I'd love to have a way to compare it to a similar but all stock 2WD TB with 3.42 gears.

They must have scrapped the airfilter dP indicator doohicky for 2005, unless mine had one that someone yanked. :undecided She runs just as good on the new filter as she did on the "sand" filter.:eek:

The factory AC delco filter is more than adequate for the amount of air the 4.2L needs. What is the point of letting in more dirt than necessary? AC delco's are the BEST at filtering dirt out of the air, it has been proven! I find it pretty amazing (and quite a testament to the quality of the factory filters) that you found no signs of sand or dirt in the intake tract after you found the original filter packed with sand.

K&N is just marketing bullsh*t.

Check out this http://home.usadatanet.net/~jbplock/ISO5011/SPICER.htm (http://home.usadatanet.net/%7Ejbplock/ISO5011/SPICER.htm). Just one of many tests available on the internet that prove my point. :)

[thecarbonman]

I changed mine to an AIRAID and find it to be the best air filter I have ever used.

The filter I took off looks EXACTLY like the FRAM 9345 filter I just bought from Walmart for $13.74. No AC Delco markings on the original.

I shoulda went to wally mart! :duh: Fram air filters are one of the better ones to boot! I dont buy fram oil filters due to problems I've had in the past, but air filters, definately!

After reading the above link, I pulled my K&N filter out and replaced it with a Frame Filter. I hate dust getting into an engine.

I can't see the point in a K&N. It costs $60 plus the cleaning kit (let's say $15) totalling $85. For that price I can buy 6 OEM filters and still have money left over. 6 filters will certainly last me the term of my lease and keep me going long after. I don't have to worry about the oil doing any damage, I don't have to mess with cleaning it. Some people say they get performance benefits, however I've only seen "butt dyno" results, nothing from a real dyno. I'd like to see how many hundreds of a horsepower the K&N gives. I've heard talk about getting a couple tenths of a mile better gas mileage, but that's always after replacing a dirty filter with the K&N, any clean filter will give a boost in MPG when replacing a dirty one.

I can attest to over 2 miles per gallon better. I have had the filter for the last 10,000 miles. The original filter was in there for the first 12,000 miles. It still looked clean when I swapped it out. :m2:

I'm getting over 2MPG better mileage just by changing the air filter with an exact copy and changing the oil (the old oil was 5,000 mile old Mobil 1 so it was still in it's prime, so I don't think changing the oil did much for mileage).

I understood you. I am saying that at 10,000 miles, without cleaning it, I am getting 2 miles more per gallon. I am comparing dirty filter to dirty filter so to speak. If I clean it and measure it, it would probably be a bit higher. My original measurement on the stock filter wouldn't be a fair measurement cuz the engine wasn't broken in, and I was driving it like I stole it. The K&N has saved me gas, of this I have no doubt. Now...I will say the butt dyno noticed something when it was new, probably my imagination though, or it was just the return of the air that was being blocked by the old dirty filter. I would also like to see a dyno result on this.

Eggzakary what I do. :thumbsup:

[inphoenix]

So I live in Phoenix, and drive the V8 w/DOD, the K&N scares me because of the dust down here and I bought this one, not leased. I can see the I6 doing better with more air, but with my V8 I'd like to hear from someone who has done it.

[lacer_2005]

I just replaced my OEM with a K&N...it was $62 IIRC.

[garym1a2]

Funny thing happened after I took out my K&N filter, my gas milage did not get worse. Seriously, with all the press nowdays about SUV's and gas milage. Don't you think if gas milage would increase by 2 mpg with a simple filter change that the OEMs would come out with these improve filters? The OEM's spend a fortune on increasing Mileage of their cars.

The tube leading to the throttle body is probably more of a restriction than the filter itself.

Exactly.:thumbsup: K&N makes a great product & are the way to go if you are looking for 'looks' and sound quality. That's about it.

You forgot increase in torque/hp ;)

[blandmiller]

I have more than "butt-dyno" results...........

[03slt_soccal]

i did not feel anything from the k&n cai. just the noise and loss of mpg, but i like it so i keep it on :D

[New to TB]

I have more than "butt-dyno" results........... Are the results encrypted in all those periods?

[blandmiller]

No they are displayed and described in depth on another forum. I attempted to upload the dyno charts to this forum but they keep disappearing.:no:

[blandmiller]

Here you go. If you want to see the actual charts send me a PM.

I started with my current setup; 20" ASA BBS wheels, Airaid 'cold air' cone filter intake, and the Borla cat-back exhaust package.
Result 202ft# and 207Hp

Swapped 20's for the stock 16" alloys (20's were 15# heavier ea.)
Result 213ft# and 216Hp

Left 16's on and swapped Airaid for stock air box.
Result 208ft# and 209Hp

16's on Airaid intake tube, no cone filter.
Result 215ft# and 217Hp


Hail mary dyno pull: 16's, Airaid (filter on), uncork exhaust behind cat.
Result 218ft# and 221Hp

They probably get deleted here because they are not allowed in the photo gallery, only pics of your truck.

I'm a little confused by your results, where are the results from the K&N air filter and where are the results from the stock air filter?

I see that you mentioned the stock airbox, but was that with the K&N or the stock filter?

[Prey521]

You must've installed it wrong LOL

[blandmiller]

None of my gains were from a K&N filter. All of my comparisons are stock air filter/mounting to the Airraid CAI installed.

[dh4645]

whats the deal with this?

from a K&N product page:
The K&N AirCharger Kit is NOT street legal on pollution-controlled vehicles in some states. The kit replaces the OEM filter box and may eliminate or defeat emission controls.

Seems like a typical liability disclaimer.

[mluntz]

Does this mean that if you install the K&N, and you go for an emmissions test, you could possibly fail?

[New to TB]

I would assume only if A) your airbox had a device that controlled emissions (which the TB doesn't) and B) you lived in a state which required emissions to be controled by that device (which I doubt you do).
