Default Drilled airbox benefits?

Other than sound enhancenment any additional benefit re cooler engine temps. Fister stage II's already installed will drill airbox sound even be noticeable?

zero power, probably a degree or two warmer air temps, but a slightly nicer sound

Actually,.........there IS a tiny power gain as measured on our Superflow engine dyno,.... We did test this exhaustively on several 3.6 engines using stock and modified covers and each time we saw a 2-3 BHP difference.

While one cannot feel anything that small in one's gluteous maximus, the results are clear and thats precisely why dyno testing is so important.

In the car, no air temperature differences were noted using the PST-2 over a wide range of conditions while driving down the road. Engine compartment and intake air temps remain at ambient when the car is moving faster than 30 MPH.

fair enough, although as you noted, 2bhp is pretty difficult to feel

Impossible to feel, however such things being incremental contribute toward the total results when other tangible and worthwhile upgrades are done.

A good example would be adding RS cams & intake valves; doing the airbox modifications adds to the total benefit.

I had one of those faux "carbon" after market airbox covers that leaves the entire filter exposed, also leaving the clutch vent exposed to the engine compartment, the air filter prone to collapse, as well as what i anecdotally perceived to be a FOD (water) intake hazard... plus it has no clips to secure it... I swapped back to the OEM one, i felt no difference in power or sound going to stock, other than peace of mind....

I really dislike that chrome trumpet trim. It looks like it came from Pep Boys.

You'll be able to hear it over the exhaust. I love the Motorsound intake noise.

I'm assuming that had the intials FS? I think those are the biggest POS intake setups I've ever seen. I've known of a number of 911 folks that bought those, and were pretty disappointed in how they blew $200.



I don't think the chome horn looks out of place at all-it may offer a little zip to an inocuous looking motor. It wouldn't break my heart if the Motorsound cover had a black horn, but the chrome part doesn't effect me one way or another.

Two horsepower here, four horsepower there. Like removing weight, the benefits all add up assuming a comprehensive power/diet program.
