I got a couple Z32 MAF sensors I don't need anymore.
Used OEM Z32 N62 MAF - $sold
New ISR Z32 MAF (Part number: 22680-30P00) - $115
These should fit a flat rate box, so I can ship.
Went with a MAP system so I do not need these anymore. I bought the ISR MAF as a form of preventative maintenance right before making the switch to MAP so it never saw use, and it is in new condition. Price on Enjuku is $145, so this saves you a few bucks.
