If you are looking to get the best signal and flow out of your MAF sensor, most tuners will tell you to upgrade to an LS7 MAF sensor. Well we just made the job that much easier! Our conversion kit includes everything you will need to easily change from your L76/L77/LS3 Style MAF sensor, to the better LS7 Card Style MAF sensor in minutes. With this kit, you will also increase the flow of your current intake system due to the larger diameter (4″ vs. your stock 3.5″) aluminum MAF tube.
