Cost: $55
Time: 5 minutes
Theory: The stock throttle body inlet tapers inward a bit, which hurts high performance engines. Although my car probably is not to the point where it made much of a difference, the inlet was on my list of items to get and the price was reduced, so what could I do?
Opinion: The inlet is of good construction, but its clean look makes the engine look dirty, haha. Installation was extremely easy, but now the engine is demanding I upgrade to a new turbo...
