How To Fabricate an Air Intake With a Blade Style MAF Sensor Using a Flowmaster Universal Intake Kit

Getting the air into your engine used to easy, just slap a chrome air cleaner onto the the carb and go. Today's EFI engines are more complicated and require special tubes, sensors, and placement. The MAF (Mass Air Flow) sensor alone can cause all manner of problems. For LS and LT swaps, blade-style MAF sensors are the most commonly use, but too often just put anywhere, which can lead to poor performance and sometimes they won't even start. The specific location for LS and LT engine MAF sensors is as follows: 4" diameter tube Minimum 10" from the throttle body MAF placed in the center of a 6" straight section MAF must be located in the top half of the tube, preferably at the top. Our 1971 Buick GS Convertible project has a new LT1 crate engine, now with a D1SC Procharger strapped to it. We needed to connect the intercooler to the throttle body, and put the MAF sensor inline with it. We are running the MAF after the blower, after the intercooler and BOV, near the throttle body. This allows us to use the inlet tube as a standalone while we are not running the blower, and then keep it when we connect the blower after the LT1 has some miles on it. Jefferson ordered a @FlowmasterInc Delta Force universal air intake kit from @HolleyPerformance and built a pip for the GS. These kits are great, as you can usually get two or even three vehicles done with one kit (you will need additional filters), so the $430 dollars goes a lot further than you might realize.
