Cold air kit with stock air filter


Recommended Posts

Howdy to Loren and all other fellow CAR-NUTS! :D

I'm thinking of modding the airbox (e.g. Fabspeed cold air kit) to increase the amount and quality of engine music. Throttle response and claimed hp gains are not my objective. I'm simply looking for mo betta sound.

I'd like to run the stock air filter with the mods that replace the MAF plastic grate and eliminate the stock airbox muffler.

Does this combo make sense with stock ECU programming with respect to air/fuel mixture, potential flat spots in the power band, etc.???

BMC/K&N filters are not for me. Too much controversy over engine contamination, oily MAF failures, and cracking rubber surrounds.

Thanks for the input.

RJ you're starting down a slippery slope....:)

Intake systems can potentially make some good horsepower or lose a lot more power. Stay clear of the "cone" intakes, there is no power to be made with hot air. The NA 996 is the same as any other NA engine in that it will benefit from colder air induction, it's nothing new as the muscle car era is a good example ("Cowl Induction", "Shaker" hoods, "Grump Lumps" etc..."). We saw a solid 5 HP at all RPMs on the dyno on our old small block racing engines with adding a stack to the carb attached to a hood scoop. So there may be some power to be had on the 996 too, this has been shown on PCA class 996 race cars.

But if you're after improved sound then I think the Fabspeed is pretty good, some people even make their own setup but I could never find the right plug. Maybe Loren can help with that part.

The only thing I might worry about would be the potential for a CEL.

This thread talks about the plug. I installed it a week ago and like the slight increase in engine music. :clapping: And they'll send you a free sample!

Poursha,

I know about the orange caps, but I would be more comfortable with a "locking" type plug that won't dislodge. Plus, I'd also like to get rid of the stock airbox silencer/muffler to increase volume in the intake chamber.

One of my real questions is: Will the stock ECU be able to adjust favorably to higher intake volumes, or should I expect flat spots and CELs?

Right now I'm sticking to the stock air filter...

Most of the aftermarket guys will tell you need to remap to take advantage of the increased intake, and in your case outflow with the mufflers, for more bhp But if it is just sound you are looking for I personally would not remap.
