ok what about oil foam filters like uni filters on the end of a tube

if you want more power, put a v8 in it, otherwise leave it alone.

nobody has talked about the AEM dry filters yet,they sound good for a drop in app?mentioning foam makes me think i might do a foam prefilter as well since my filter gets very dusty very fast.like almost a 1/4" of crap sometimes

a properly maintained and oiled K&N filter is more than sufficient to protect your engines internals and will not contaminate any of the upstream sensors. ive had my K&N drop in in my truck for over 3 years and about 20,000 miles and my MAF sensor looks just as clean and dry as the day i cleaned and dried it. my truck spends the majority of its time these days towing and hauling or driving on the beach. as such, my requirements for my filter are higher than many, but it performs as desired.

i would be more worried about a FRAM air filter letting debris into the engine than a K&N. ive seen FRAM air filters that dont properly fit inside the air box they were designed for, thus letting unfiltered air into the engine. at least my K&N has a high quality frame and seal that will hold its shape.

i didnt expirience any power or mileage gains with the K&N because there are none to be had. i got the filter because my truck sees a lot of heavy use in dusty/muddy/sandy conditions. it has already paid for itself in the money its saved me from buying paper filters. since i plan on keeping my truck for a long time, it will continue to save me money.

^^^ Agreed. I regularly check and clean my oil filter. I have had mine for several years now as well.

the oil is the key on the k&n filters fun dry and ull regret it

 

[rickcdewitt]

it sucks to scrape a 1/4" of oily crap off the filter and spend the rest of the day cleaning and drying it.just one weekend on dusty trails is enough to suck the oil out of my heavily oiled k&n.

nobodies tried an AEM dryflow?it would be nice to just whack it on my leg a couple times and pop it back in

just get a snorkel if you want cold air

And you'll get more power from a "Type R" sticker. Every Honda owner knows that.

Do I hear new sig... I think so
