ISR Performance OE Replacement Mass Air Flow Sensor (Nissan 300ZX)

ISR Performance OE Replacement Mass Air Flow Sensor (Nissan 300ZX) These are a Must when doing a turbo upgrade on the SR20DET or KA24DE  If you are upgrading your SR or KA you will need a Z32 style maf plug, Z32 MAF adapter, and to have your ECU retuned to utilize this properly. ISR is the first to bring these OE Replacement parts to the US. This would be just like getting a new MAF From the local autoparts store, however they no longer sell them, or require a core.  These are BRAND NEW and not refurbished!  Dont spend $600 for a new NISSAN one.
