iWire’s Hybrid MAF (Mass Air Flow) Adapter for 2015+ direct-injected, turbocharged Subarus allows you to motor past the limits of the stock mass airflow (MAF) sensor. Our Hybrid MAF Adapter is a plug and play solution to allow for MAF based tuning at low speed for good driveability while switching to Speed Density at high speed for more power when the MAF becomes inaccurate. There are no additional sensors to buy. Just plug it in, get a tune, and you’re up and running.
Our adapter is built to last with Mil-spec grade materials like flame retardant, corrosion, and abrasion resistant Tefzel wire. We've also wrapped it in Raychem DR-25 heat shrink tube that can withstand the harsh environment of the engine bay.
