Cold Air Intake...Which one?

ffden · 07-30-2007, 06:36 PM

I've done a lot of reading on CAI's and can't decide which one to get. I was looking for one that will improve air flow and adds HP and Tq but is reasonably priced. I also looked at modifying the stock airbox with PPE's suggestions but need to find an aftermarket re-usable filter element. Any suggestions?

AFE proguard 7 filter is pretty good. I believe AFE also has one that isn't oiled. S&B I hear is pretty good along with the filter from amsoil with the nanofiber technology.

I don't know much about these...but I had alot of people tell me NOT to buy a K&N system. They say it lets too much dirt in. Hope this helps some.

AFE or S&B,i did the PPE air box mod on my LBZ and it's pushing 420rwhp and i really don't think it needs more air and that is with the OEM filter but if you would rather do the after market filter then go ahead but i figured i give you my thoughts..

that is true, k&n are good for gas engines, but not for diesels. good ones would be afe, s&b, or volant. but i'd go with afe, IMO.

One of the reasons that I would not do the PPE air box mod is that OEM filters here are $92 at the dealer. 4 of them will pay for a limetime re-oiler sytem. Sounds like aFE Stage II will be my choice unless anyone can suggest otherwise.

Ill throw another vote in for AFE. However, I think the stage II is a waist of money. If I were to do it over again Id use the extra $100 to upgrade to the proguard.

The only thing different you get with the stage II is the useless "torque" tube thats no different from the factory tube

Thanks Tow Master for the info on the Stage II. I read an article in Diesel Builder mag Aug 07 " 18 HP in 18 Minutes" about the K&N Intake System. It seems like a nice system and alot cheaper than the aFE and Volant. Why is the talk on this forum trashing K&M and what is the problem with them.

Hey sure thing.

I personally think K&N makes a great system! Alot of People say that K&N filters are less restrictive and let more crap through. So with the turbo's you dont want ANY debris hitting the veins. I think the price for a kit is like $250.00? So there one of the cheapest out there and from what I have seen they have the most known brand name. When I got my AFE K&N was one of the top 3 brands I was looking at. But I started reading and it seemed that AFE's ratings are better and you get a little bit more power so I went with it. Id still consider K&N.

k&n lets too much dirt in compared to afe.
