Not a fan of this, at all. SAI is one of the best emissions control inventions ever, and dramatically reduces NOx and CO emissions with ZERO cost to performance. Its downright asinine to 1) remove and 2) advocate the removal of this device just to make your engine bay look cleaner. And seriously, do you think anyone else will ever notice?
I'm hoping that you just don't realize why SAI is used. The VAST majority of harmful emissions produced by cars occur during the first few minutes while the cat's get up to temp. And by VAST, we're talking upwards of 90% in some situations. The SAI is there to speed up the heating process. This modification will significantly extend the amount of time required for cat's to heat up, and will result in, ballpark, 5-20x times more NOx and CO emissions.
Basically, you're now pumping out more toxic gas than an 18-wheeler semi. And for no reason, at all. Great job.
