air filter

[garyldill]

has anyone tried the K&N air filter. The local parts store has them for around $40. Do they improve hp. by 10% as they claim? gary.

Hi Gary,

K&N has been discussed numerous times here. Use the Search button located at the top of every page - you'll get the answer to your question.

I agree about the search but, I have tried the K&N on my Insight. Didn't notice an improvement (in power or mileage), after a years use. So I went back to the OEM air filter.

I don't quite understand switching back to OEM as I have read in some posts. If you can avoid replacing an OEM many times over vs. K&N, why not do so?

There's an old thread on the topic, recently revived:

MPG, Who has tried a K&N air filter on the Insight

Please follow-up in that thread if you wish to continue the K&N discussion.


HTH!

I have a K&N filter on mine, and found that there was a smidge more power (maybe), but milage has also gone down a smidge.

I believe that the test where they got a 10% HP increase was with a car that had a 454 cubic engine.

Because if you reuse it and over oil the filter damage can occur with the intake. Other manufactures have already denied warranty claims when techs observed this oil on a cars MAF screen. The filters are great but some owners can't seem to get the re-oiling down.

From my experience there just isn't much (if any), noticable improvement with a K&N filter for the Insight over the OEM filter to be worth it.

Thanks for the heads up. I have about 45,000 miles to go on mine. Guess I will determine at that point whether I want to attempt re-oiling, flat out buy another K&N, or go back to OEM.

Since Honda's aren't equipped with a MAF (they use a MAP system) oil is not a factor!

With that said its not foolproof. Install your K&N literally dripping with oil and your could foul a spark plug sufficiently to require removal for cleaning or replacement. And ignore a misfire long enough from a fouled spark plug and you can melt down the CAT.

Yes, this is an _extreme_ example, but I've seen CAT's melted down from similar causes

HTH!

I have one in mine and didn't notice any difference per say.
