i'm using this faq, http://www.drwebdesign.com/mymaxima/upperintake.html, to make my own CAI. what is the part# of the K&N air filter that will work best with it? thanks

 

Yeah, same here...I'm thinkin of doing this but i dunno what # for k&n it is??

 

i did that and used the K&N filter part #RU-2820 but there is another one that work that is actually a cone that i dont know off the top of my head

 

If you're not particular about the K&N brand, APC makes a cone filter that has a rechargeable element called the APC Intimidator, available at many auto parts stores. Any cone filter with a 3" inner diameter base will work.

I bought the APC filter for about $20 and then bought the K&N cleaning/recharging kit.

 

IMO i never really liked APC.. they seemed more for Civic owners and most of the stuff i see at auto zone and pepboys look cheep.. but hey it all a matter of what you want for your own car, so what ever looks good and makes you feel good about your car

 

thanks. does anyone know the K&N cone part# by any chance?

 

think its RU-3580 or RU-3700

has all the measurements we need a 3" diameter opening

 

Here are some directions on how to install the Price Racing unit... which is pretty much the same thing as the Bomz. However, the Bomz does not come with the template used here. But, it's probably not really needed, as the piping can be installed first, and the location of the hole can then be 'eyeballed'. note... The page below is NOT mine. The fellow at the site gets the credit.

I purchased mine from ebay, and it looks just like this one. It seems like a nice setup with powder coated 3" aluminum tubing. It's only drawbacks are the plastic MAF adapter and generic filter... but the piping is worth the $50. Hey, if you don't want to use the cold air part, it can be left off and you'll have a hybrid intake. The metal sleeves for the connectors are cool too.

I made my own MAF adapter out of a piece of 3/16" steel and a short piece of 3" exhaust tubing using a welder, grinder and drill. I also plan to purchase a K&N filter #RE-0930 that measures 6" wide at the mounting flange, is 6" long, and is 4-5/8" in diameter at the end. I'll also be using a pre-cleaner to shield the filter from road debris and keep the bigger stuff out of it. It's part #22-8033PK

The filter costs $39.26 and the pre-cleaner is $15.99 at http://www.4filters.com They charge only $5 shipping on any order.

Good Luck!
