I left my car at the shop to get a throttle body installed today and the NSX guy there suggested this little mod to simulate exhaust sound. It sounded fine in the pretest and we made sure that it's small enough to not lead to HP loss. A 1" by 5" rectangular opening at the bottom left hand corner of the airbox was cut open, leading more air to the MG Racing filter. At 5K rpm and above, the car now generates IMO a very deep, bassy note that's loud enough but won't wake up the neighbors. Both jobs cost $130.

Hot air?

 

definitely not as hot as $1,500 aftermarket exhausts on rice cars

 

I think he meant your airbox is now sucking in HOT air from the engine bay. You'll lose HP.

Some people on the board have dynoed their car with the top of the airbox off( makes the same sound as you've described) and proved that you lose HP.

Cold air is better.

how much did you spend for this job? you sir are retarded!!! could have spent an extra 100 bucks and got a cold air which will make your car a bit louder and increase horsepower

 

this thread is from 2001 man hahah

 

Or just taken off the lid to your airbox

 

Sounds like you're only intrested in how it sounds more than any small HP loss, so its all good if you like the stock looking engine bay. Thou a CAI would've gave you a more refine sound, plus cooler air

Very old thread, just notice

 

How the hell do you guys stumble upon these old threads and not realize they're extremely old?
