Cold Air Intake

A6 Pilot,
I think you information on K&N is a little out dated. See http://www.knfilter.com/air_filter_testing.htm. They now have numbers that come from actual test on actual vehicles.
JMHO.

Nothing for the Pilot.

This information is kind of interesting:

Hello Everyone,

I'm new to this Forum, so hello. I've been looking all over for answers on Cold Air Intakes for my 2007 Honda Pilot (2WD). Does anyone know why there aren't any, or if we can adapt the intake that goes on the Ridgeline to the pilot without problems?

From posting on the Corvette forums for years, I've come to the conclusion that you will hear many opinions and data on how filters and cold-air-intakes perform.

So, I will try to keep it short and let you be the judge.

First, since you have a 2WD Pilot, if you read the manual, you have an "intake tuning valve" in the intake manifold.
That valve switches position at around 3K, or maybe it's 4k, rpm to change the effective intake manifold runner length to give a performance boost at low and high rpm -- think of it like a poor man's supercharger. It is a clever idea, which I wish I could modify and put on my Corvette.
The 4WD Pilot doesn't have it -- it has variable valve timing instead. The 2WD Pilot doesn't have variable valve timing.

Second, for what is worth, I paid $75 for a K&N filter for my highly modified 1992 Corvette.
After about 1K miles and testing with various scan-tools, to detect intake manifold vacuum, at WOT (wide-open-throttle) and dyno testing, I took the K&N filter with 1K miles and "gave" it to another Corvette owner.
My testing showed no improvement at all and I didn't like the fact that the oil was being deposited inside my intake.

Roadie96720-

If anything the K&N site you referenced kinda proves what a lot of people are saying about K&N filters. Test results that are done in house should be suspect. Independent testing should be the first requirement. Note, also, there are no results listed for the Pilot.

My comments about K&N filters are a result of having bought one of their filters. I took the bait. Sorry I did. Complete waste of money. Fair warning......

I HAVE a K&N drop in and don't care about performance. I like a re-usable filter and I have tested my oil in previous vehicles and didn't see any change in Silicon content. Also OEM would never put something like a K&N filter from the factory, think of the $$ they would lose in service and the whole service industry would cry "they are screwing me out of a job". Would YOU be ok taking your car to the dealer and PAYING 1 Hour or more to have you filter cleaned and re-oiled? Just my $.02

The "independent" tests show exactly predictable results - better "cleaning" - less air gets through. Look at the first graph, and at the last - same filters, same order. Better filter filters a dust - less air is getting through. As we discussed, to get better performance, you have to get more air. So, with "cleanest" filter your engine will get very clean air, but it will "starve for air". In opposite, if you get "high performance filter", you will get more air by sacrificing an air quality.
