K&N for the 80's (1 Viewer)

[cary]

According to the reading I have done, K&N filters allow more dirt into the engine than a plain paper filter. So why do race cars use them? 1) They flow slightly better, and 2) the will continue to flow better as they load up with dirt, and still flow air when a paper filter would be clogged. Note that off road racers that use K&N filters, also use pre-filters. Also as mentioned, these same people are concerned about their filter flowing through a race, not getting 200,000 miles out of their engine.

As far as performormance gains, there are none, and potential downsides of more dirt in the engine and gummed up air flow meters. Put the $40 into something else.

The main advantage I have seen with a K&N is on my quad. We were riding for a long weekend in upper michigan on very sandy trails. The one bike without a K&N was done on the second day. OEM filter and backup were hopelessly clogged. The rest of us cleaned and oiled every night. Again, way different needs from an 80 series.

You can't use Harley guys as an example. Those guys spend all their money on clothes, chrome and noise. If one of them put a part on their bike that did nothing else but improve performance, they'd be kicked out of HOG.

I use a K&N in my wife's Audi A4 1.8T. It's moderately chipped and the boost is now 18 psi, up from the stock 7 psi. I noticed a small improvement in power with the K&N. Downsides are that sticky oil tends to coat the inside of the intake tract and intercooler and TB, and it is not quite as effective in filtering as the oem. Since she doesn't drive in dusty conditions and only goes maybe 8000 milers per year, any decrease in engine life is an acceptable compromise. So what if it wears out at 175K rather than 200K - it will be 20 odd years away and we likely won't own the car then

OTH, I run the stock paper filter in my LX. Unless I installed a super- or turbocharger I wouldn't consider any other filter.

Doug,

I don't know about tampax air filters.

But their pantyliners make a good emergency water filter to keep floaties out of the radiator. Just pull the plastic off first.

I tried the K & N and the TRD air filters. No change in performance. Just a pain the reoil and worry about the dirt getting in. Just use the stock filter.

My 2 cents...

Ran a K&N in the stock housing...no difference, more oil and dust got in.

Ran a K&N in a home made RAM setup, no difference, louder, less oil and dust got in.

Ran stock setup all tightly fastened and replaced all rubber components...improved performance and no dust got in.

I tested all these setups over a period of several months each. I am not sponsored. I am not a Harley owner...and you are wrong

Since this is titled K&N's for the 80;
I was planning on using a K&N Oil filter for the LX450, like I do in the 40. The K&N was a better oil filter than the crapo FRAM. Is there any reason I shouldn't. Picked one up at Pep Boys. Small filter compared to the 40.

Ken,

I respectfully suggest that you use only Toyota OEM oil filters aquired from your dealer of choice. I do not care where you source them, only that you use them.

Same here, Ken. It was Raven who ultimately talked me into dumping the K&N and going back to OEM, though many others will concur and I stand among them. IMO a little extra dirt isn't worth a little extra MPG... I plan on using this engine for many years to come. -tim

I thought this should be posted in the 80's section also, this should put the final nail in K&N's coffin

I would suspect that the Toyota filter would perform similarly to the AC-Delco, they are both well made filters with lots of surface area compared to aftermarket filters (ex chevy owner)

Mine im using JAOS filtercharged which totally different than any other air filter out there.
Also by chance to getting so much dirt is very minimal because its drop in not like those open air filter. The different is JAOS use sponge material not (paper like those factory filter or K & N Filter)

The other day i was thinking to get this but probably with open / free flow may suck all the dirt, etc.... http://cgi.ebay.com/ebaymotors/ws/eBayISAP...&category=33659
