K amp N CAI vs Stock box with K amp N filters

[Vprbite]

Any thoughts on the K&N CAI vs just putting the K&Ns in the stock airbox? I know the Gen II K&N had a design flaw that just pulled straight from the hot engine bay but that doesn't seem to be a problem with this one.

If nothing else, it seems to be the equivalent of "smooth tubes" for the Gen III.

Just wondering if anyone has experience with it vs just putting the K&N filters in the stock airbox.


Thanks for your help, VOA.

Merry Christmas!!!!!

When I had my '08 Gen4, I did the Mopar PCM and Belanger Headers and the car felt strong with 575 Rwhp, up from 545 stock. I then tried the K&N CAI and did some back to back same day Dyno test, only to find that the engine lost power with the K&N CAI! It looks good but did not help power, on my test anyway. See Dyno chart below.
The drop in K&N filter in the stock air box, did not gain HP either but was about equal with the stock paper filter.

For the Gen IV, the K&N will lose power...or not gain any.

The Gen III will benefit from the CAI. Not sure about just replacing the filter. I would assume you'd get a little bit better power with the complete system because it makes the air flow more direct and smooth.

Basically my filters are dirty and stock ones are 150.

So for 250 and change I can do the CAI from Jon. 100 bucks for 10hp isn't too bad. But I wouldn't want to lose power of course.

For the Gen III, it uses the factory airbox so it appears to be basically the filters and a "smooth tube" instead of the accordion tube coming out of the airbox.

I was also finding it hard to except the price for a stock paper filter. I noticed on http://roeracing.com/OE-Parts/2004_Viper.pdf they indicate mopar part number #P4510940 as a "Performance Air Filter". They were half price compared to the paper filters, I even bought them from the dodge dealership they were so cheap.

They are basically a k&n filter (cotton filter). Fits perfect, looks kinda cool with a blue filter, I highly doubt that the k&n filter would out perform it. When you shop for them, dont let the cone shaped images on the sites fool you...they are cylinder shaped... exactly like the stock paper ones.

Unfortunately, I did some exhaust work and the air filters at the same time, so I cant give an accurate indication if the car feels any quicker due to the air filters. If you want a picture of them installed, let me know. Here is an accurate picture http://www.moparonlineperformance.co...p/p4510940.htm

For best results add the roe single blade tb at same time and you will be amazed at the throttle response

I've never understood how oiled filters get better air flow?
I just seems that if the filter has oil on it, that, in inself is restrictive?
Yes blue filters do look cool on blue cars.
Green Filters USA offers not only green color, but red, blue and gray. Direct competitor of K&N.
Not sure if they are better than K&N but the green sure looks nice on my SSG.

Green are oiled, right BillyC?


Anyone know which ones are required for a 2006 Viper? On their search, only the SRT ram comes up and it's a different filter.

Thanks!

Thanks! I'll take a look at these. Perhaps I'll order them now at that price.



And BMW2nv2000...I was definitely considering the throttle body

Thanks for the heads up on these. This might be the way to go. I can't imagine them being worse than OEM and be always found horse powers gains from filters to be pretty bold.

It seems like anything besides OEM is oiled.

Thanks for all the inout. It is greatly appreciated.

This was my thought. And the unit itself is not very expensive. The filters make up the bulk of the price.
