Seems like the more I look the more confused i get. Was told today that you can put a k&n filter in a stock intake and drill some 1" holes in bottom of intake and it will work as good as amy after market performance syste. i dont believe everything I hear but sounds interesting. The guy pulls his truck and is successful....any opinions? Thanks

 

Some will disagree BUT a K&N is definitely NOT the best option on a Cummins. They let in WAY too much dirt.

As for drilling the holes in the airbox, yeah you can do it and get a bit more airflow but the fact is, the airbox doesnt seal well at all and this isnt a good option either.

A much better option is a paper BHAF with an outerwares racing prefilter or SCOTTY 2, or an AFE stage 1 or 2 intake with the Proguard 7 filter, all of the above get rid of the crappy stock airbox.

Dr. Evil...

in those pictures of the BHAF where did you get the cover for the filter and the heatsheild...

Thanks...

 

Not my setup.....its Phoxes.

But you can get them at: http://www.outerwearsracing.com/

Give them the BHAF part number and color you want and they will ship directly cutting out the middleman.

 

Thanks, Doc for saving me the time. I spend a lot of time warning against K&N.

Take a looksee here http://www.unifilter.com/automotive.htm

UAP-908 4" 6 1/2" 5 1/4" 11" $49.95

I run this in my truck. UNI is a great filter company. Well known in the motocross/dirtbike, atv, offroad racing crowd. Oil Foam filter.

 

If you do a site search you will find the heat sheild template.
And you will also get the BHAF part #'s as well as the pre filter #'s

 

UNI is what I use in all my air intake applications.

 

If I would have known my setup would be referenced so many times,
I would have cleaned up a little before I took the pic.


If UNI is good enough for Scotty, nuff said.

I'll stick with my goofproof paper filter, at least for a while.
