Torque Solution PNP Hybrid Speed Density Adapter Harness allows you to easily switch from MAF setup to Speed Density without having to hack up your OEM harness. Our adapter harness is a direct plug and play with the OEM harness plug and GM Style IAT sensor, such as AEM part# 30-2010. Requires a bung to be welded for the IAT sensor either on the throttle body side of your TMIC or on your FMIC upper charge pipe right before the throttle body. This hybrid harness provides your tuner more flexibility in tuning between MAF, Speed Density or a combination of both by providing the most accurate intake air temps. This harness is best suited for vehicles equipped with intakes still utilizing the OEM MAF sensor.

Manufacturer's Warranty — Torque Solution
Torque Solution states a Limited Lifetime Warranty on its manufactured billet aluminum and polyurethane parts — engine, transmission and differential mounts, shifter and suspension bushings, blow off valve adapters, exhaust hangers, flanges and fittings. Its electronic parts (Fast Response IAT sensors and PNP speed-density adapter harnesses) carry a 1-year warranty instead. Wear and consumable items — turbo blankets, intake gaskets, exhaust wrap and heat tape — are sold without a stated warranty term. Coverage applies to the original purchaser against manufacturing defects; check the individual product listing for the term that applies to that part.
Warranty terms are set by the manufacturer and may change. Full details and claims are handled directly by Torque Solution. Contact us if you need help with a warranty claim.
