ne specs on the filter though....

its a K&N RX-4750 iirc (or something with a relative model ##)

No, INTENSE doesn't use that. I have the first 'test fit' 4750 on the SLE now. It'* a 3" flange. INTENSE'* is a 3.5".

The Intense FWI comes with the 9" Kaf-920 cone filter.
The drop in filter is 33-2086


BTW - isn't your intake 3.5 inches?

I gutted the airbox (will be cleaning up the junk inside, though) and dropped in an Amsoil EaA 8 air filter. It made a difference in throttle response, and almost no change in sound.

Mine? 3.5" FWI on the Zilla
Zilla'* old ADTR 3" prototype on the SLE. With the old original RX-4750 still going strong.

Here'* a thought...

I'm curious to know if a stock L36 would be gaining anything with a 3.5" intake...doesn't that seem a little excessive for a stock N/A engine?

IMO, he should start off with a smaller intake or preferably a gutted airbox, then work his way up until the 3.5" Intense FWI would be more useful. Other mods would probably be more beneficial at this point.

Correct me if I'm wrong, of course.

I personally think INTENSE has probably done their homework on a dyno. And I know many L36 owners are very happy with their FWI'*.

I also know the TB diameters, and the flow at WOT for each gen of 3800, based on their max RPM before shift.

Yes, it'* properly sized.

Intense does plenty of dyno testing but I doubt they tested the difference between a 3" and a 3.5" intake..

Horsepower is proportional to the flow through the engine. And given the stock hp of a L36, I find it hard to believe that it flows enough for a 3.5" intake..

If you are really tight on cash, the INTENSE FWI might be a little steep for you. Search for "cai" in Performance & Brainstorming and you will learn all you need to know about cold air intakes, and heat shielding. Many members have assembled their own and cobbled together nice heat shielding that works pretty well.
