I think its 87-89. It looks identical to yours but has a "A" on it instead of an "S". Check ebay they are sometimes on there for cheap.<p>INFO from Vaughn's website:<p>RX-7 MAF Sensor on "B" Engines<p>One of the biggest bottleneck in making power with the "B" series engines is the restrictive "Trapdoor " type MAF sensor. The second generation RX-7 Turbo uses a higher flow sensor design that is easily adaptable to the "B" series ECU. The connector pin layout is the same and sensor values are more of less the same values. Being larger you will need an aftermarket cone filter adapter as the If your engine is unmodified and/or will not see anything above 6000rpm, then you shouldn't bother with this modification as it will be just a waste of your money. A header, muffler and a cone air filter will not increase the airflow requirements of the engine. You will only need the larger MAF if you have made modification that affect air flow requirements significantly like forced induction, over boring the cylinders, larger diameter valves, more aggressive cam lift/duration, porting the head, and a competition chip, etc. Some fine tuning will be necessary to correct the low/mid throttle air/fuel ratio by turning the small internal adjustment potentiometers inside the AF meter. You may also find you that you will need an adjustable fuel pressure regulators to correct the A/F mixture at WOT. Tuning will require a A/F ratio meter the make this adjustments correctly guessing at setting can be dangerous.<p>[ July 16, 2003: Message edited by: RiceRocket666 ]</p>
