You won't notice much difference in gas mileage. The primary purposes of bypassing the resonator and intake plumbing are to improve throttle response and pull in cold air from the fenderwell instead of hot air from the engine bay. The former is for drivability, and the latter is to help prevent knock. It also improves performance, but the difference is marginal.I am wonder if anyone has done any gas mileage test after removing the air intake baffle. Also the Pro/Cons of the noise from the Turbo.
Nick, I respect your opinion and you usually have a lot of good things to say. I've learned a lot, but please consider what's going on here. I'll trace the path of the airflow on the stock system as well as I can.According to these aftermarket air cleaner people, engineers are idiots and can't even design an air inlet system. When a lot more goes into this that meets the eye, A whole ton of government standards have to be met. So why aren't they fooling around with the valve intake timing, exhaust, ignition, injectors, intake and exhaust manifolds and everything else dealing with the emission and airflow characteristics of an engine?
Mainly because the air cleaner is the easiest thing to fool with also accompanied with major lie type claims. Only thing you are doing is hurting yourself with the warranty and even insurance companies by modifications. With the correct attorneys, if they find you even modified your air cleaner and didn't report this, they don't have to cover you, even if it wasn't were fault.
If you want more engine noise, has to be an MP3 available someplace you can play through your radio. More noise is all you are getting.
For the bypassing of the intake resonator? See the link in my signature.Can you provide a guide for us non-mechanics ?
