Review on BBK 3502 Twin 61Mm Throttle by Andrew Schobinger

This is not a product you can just bolt on and wonder! However, this is the icing on the cake. But first you need to bake the cake. If you don't understand what I mean is that you have to do all the other things on the engine that help increase the airflow that the throttle body delivers. If you still don't get it, that means getting rid of your headers and installing headers and a free exhaust. This does not mean that you have to install and be done with the cat-back system. You also have to increase fuel consumption. Get a good set of matching fuel injectors and make sure your fuel pumps are ok. Don't expect factory 150,000-mile fuel pumps to handle the load. And it wouldn't hurt to fit a good emergency ignition. And finally, increase the airflow entering the throttle body, at least install a K&N panel filter, but it is better to install a cold air intake system. One that actually pulls in cold air from outside the engine bay. Please contact your local High Performance Store for recommendations specific to your application.
