Safe & Secure

Don't cut out the stock Mass Air Flow (MAF) plug to convert to Speed Density (SD) in your Subaru. Use iWire's plug and play Speed Density harness that converts the stock connector to the new Intake Air Temperature Sensor connector.

Our harness 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.

For front mount intercoolers we provide our extended length of 48 inches of wire.

IAT Sensor:

Our Speed Density Wiring Kit works with any 3/8" NPT IAT sensor. When adding on the IAT sensor from us we utilize the AEM Sensor with weld on bung AEM part number 30-2010.
