secondary air box mod?
http://www.topspeed.com/cars/lexus/2...3635.html#main
"The 5.0-liter V-8 makes some great noises, especially when the vacuum-operated secondary air box opens up above 3,000 rpm or so. It’s almost a shame the extra noise isn’t programmed to happen at a lower rpm. (Thankfully a quick plugging of a single vacuum hose is said to keep the air box open all the time.)"
Anyone done what is suggested here? Is it safe to do, does it increase performance and/or the sound?
