JET Power For Your LS1
If you have invested big money in a high-flowing intake manifold, throttle body, and heads but are still drawing air through the stock 75mm LS1 MAF, it's time to pick up JET Performance's Mass Air Sensor Conversion Kit. Even bolt-on cars could benefit from a 90-cfm flow increase, which should add up to 10 hp. The 85mm sensor, adapter harness, and all necessary hardware are included for the conversion.

Set The Pace
Finally, front-wheel-drive V-6s get a little help in the performance department from PaceSetter Headers. The 3.1L and 3.4L '97-'03 Grand Prix, '97-'05 Century, and '00-'05 Monte Carlo and Impalas can benefit from CNC-machined, port-matched 3/8-inch-thick steel flanges, 15/8-inch 16-gauge primaries, 3-inch mid-pipes, and a stainless steel flex joint. EGR hook up is provided, but these headers are for off-road use only. Non-supercharged 3.8L models use a 21/2-inch mid-pipe. However, all applications are available with both a black paint and ARMOR Coat finish for very reasonable prices.
