Also, get a set of shorty headers and some pulleys, they will definitely help too. I also agree with the cold air intake. I am a big fan of MAC products,
The quality is excellent, their parts fit really well, and their stuff is reasonably
priced. The mac pulleys were dyno tested at 12 hp at the rear wheels,and if
I remember correctly the cold air intake is also about the same amount.
The headers depend upon equal length or unequals. Equals give a couple extra HP over unequals ( Anywhere from about 7-10 hp gain for the headers)
But the unequals are a few dollars cheaper, and a lot easier to put on.
