Replace your failing Mass Air Flow Sensor with a new ACDelco unit. See NOTE below. NOTE: When replacing Mass Air Flow Sensor, replacement of both Power and Burnoff Relays is highly recommended. Without replacing these relays, you risk possible damage to your new Mass Air Flow Sensor, as well as continued engine trouble codes. SLP Modified Mass Air Flow Sensors For 1997-00 Larger Than Stock MAF Adds Up To 10 Horsepower Flows More Air To Support Your Other Performance Mods (Up To 600 HP!) Specifically Calibrated By SLP For Your 1997-00 Corvette While your C5's stock 75mm mass air flow sensor flows just enough air to sustain its LS1 engine, our SLP Modified Mass Air Flow Sensor's advanced design can support a 600hp engine. This larger-than-stock 85mm Mass Air Flow Sensor is designed and calibrated specifically for modified LS1 1997-00 C5's. The lightweight composite sensor will add up to 10 horsepower via proper air flow metering, which is partly due to the addition of "flow straighteners" and less incoming air flow restriction. Mass Air Flow Sensor makes a great partner to our #606-758 LS6 Intake Manifold. 97-00 Modified Mass Air Flow Sensor 618-822 $199.99 Granatelli High Performance Mass Air Flow Sensors 10-15 Horsepower Gain At Rear Wheels 47% Increase In Air Flow-Able To Feed Other Performance Mods 50 State Legal Granatelli High Performance Mass Air Flow Sensor is a direct replacement for the OEM MAF sensor, just pull the restrictive stock unit off and install this free-breathing MAF sensor. Improves air flow into your 94-96 for more horsepower and torque.

If your 1985-89 Corvette has a low restriction air cleaner, exhaust or other high performance additions, you need our Custom Tunable Mass Air Flow Sensor. The stock MAF is simply too restrictive, your engine cant breathe! You set the Custom Tunable Mass Air Flow Sensor to optimize your engines performance. A simple turn of a screw richens or leans the mixture to give you the best fuel setting for the manifold, cam, runners, etc. you have installed on your engine. Instructions included. Move Your MAT Sensor To Keep Cool Gain HP Your 1985-96 MAT sensor's stock location is near a great deal of heat, causing loss of performance. Our MAT Sensor Relocating Kit moves the sensor to allow cooler ambient temperature readings. 1985-91 owners must specify Gray or Black. 1997-00 Corvettes will gain 5-8 Horsepower with the addition of our recalibrated MAT Sensor. Provides optimum timing curve an increase in total timing. Drilling required. Instructions included. A Gray (GR) Black (BK) B More Air More Horsepower For Your 1994-00 High Performance 1994-00 Mass Air Flow Housing Gulps Over 1000 CFM (Stock Units Flow Only 644 CFM) Nylon Composite Holds Less Heat, Provides Cooler, Denser Air Charge Includes O-ring Seal Set And Built-in Air Foil For Smoother Air Flow And More Efficient Fuel Use Up to 9 Horsepower and 7 ft/lbs Torque Gain Tests have proven that the quickest horsepower gains are found when you improve your engine's ability to "breath". That's just what the High Performance Mass Air Flow Housing does. Larger diameter housing provides a 55% increase in available air flow. Housing mounts directly to your stock mass air flow sensor (MAF). No reprogramming necessary. Installs in less than one hour.
