Just wondering if a basic K&N E-1450 was worth it? Horsepower gain? I used to put these things in everything I owned but do they really make much of a difference? I got a brand new one and a new cleaner/oil kit from my buddy for the cost of me buying him drinks...which I end up doing anyway! I know every pony gained in my 305 TBI counts but will it do much?

 

worth ? for performance next to nothing if any . worth , (cost effective) yes if your going to keep the car for a length of time . some people say a waste of money , others no . i have one in my car , i've owned it 3-4 yrs. . (it's my 5th 3rd gen counting 2 parts cars) my truck is a different story , i've gone through a couple of K&N filters in it . my truck is a 1989 dodge TBI V-8 that i bought new . worth it on my truck , hell yes . oh well your choice . good luck .

 

I have a 14 inch round air cleaner setup in my car, and I was wondering if the K&N filter and filter lid I had on there was actually doing any good. So I decided to do some testing and actually measure it. I did some data logging at WOT using the K&N setup and another using a cheap paper filter and solid filter lid. In both tests I am losing about 5 kPa of MAP at WOT.

 

Forget it. Paper filters are the way to go.

 

I have a K&N in everything, but my new car, it will get one when the stock filter gets dirty. I just put one in my TA as the fitler was very dirty, but I cannot say it helps as i did a full tune up at the same time. I have always had good luck with them.

 

When I was in high school I could have sworn the K&N made my weedwhacker whack my parent's weeds BETTER! Psychological effect of the KnN box looking all raced out! Well, I stuck it in the Bird last night and the car DID feel a little peppier this morning...but that could all attribute to me washing it

 

The K&N debate has always made me laugh. Try this, take out your air filter and take the car for a spin, notice any difference? If it feels the same then it's clear the fancy filter is mostly a gimmick. When I was first getting into cars I bought a K&N and didn't realize it needed to be cleaned and recharged every so often, the end result was a lot of dust was found on the clean side of the filter and so probably in the engine as well. Stick with stock, it's cheaper, cleaner and easier. Just my 2 cents though

 

I have used a K&N in my camaro for over 10 years now, have had to replace it once, now I have a few of the dryflow filters on hand by AEM. These things are a great alternative and the price is really good. Fully washable and no need to oil. http://www.ebay.com/itm/370475389255...84.m1423.l2649

Tested this on a bolt on L98 and LS1 car....sorta. L98 car I did K&N filters vs no air filter and didnt see any gain or loss at the track. So its not a restriction on the camaro TPI type box. Also did same intake on my 383 vs no filter and then 3.5" custom CAI with AEM dryflow filter and saw no gains/differences that i could measure.

I did a paper filter vs no filter on the LS1 car I have... I did see a tiny gain in track performance/et with no filter vs paper cheapies from autozone. I did a filter, no filter, filter, no filter runs at the track and recorded air conditions to account for changes.

Somewhere around 0.05-06 ET and I think less than 0.15 mph.... back to back hotlap runs so the paper filter was holding it back some. although its impossible to feel actually feel it. I plan to upgrade it to a slightly better flowing filter combined with homemade ram air to see some gains.

It may not be worth the cost, and doesnt show much ET/mph but every little bit helps if the intake side is restricted. If its not, then it probably wont matter.

 

Orr look at you back where you came from. Miss us guys down.here yet?

 

Oh as far as k&n goes I run them just for the set it and forget it aspect

 

yeah, i miss the nicer weather we had this year but its probably too hot now haha. I'll take mild summers thanks. Too bad I didnt get out to the meets as much as I would have liked. I'd love to take a trip down with my car and hit up those tracks but not sure if i'll get around to that. Its a far trip

 

I can only comment about the one I put on my 2000 c2500 truck. I took a trip to Virginia with it and averaged just over 15 mpg. I had to go again two weeks later but I put a K & N on it. With approx. the same load I averaged 18 mpg. No Noticable power difference though.
After I did not clean it as I should have I have never gotten that same 18 mpg on highway again with it as clean as it would get but am still about 16mpg.
