| This listing is for a single rebuilt mass air sensor. It fits all models of Z31 300ZX's from 84-89. The posted price does not include the 75.00 core charge. Our store will automatically add that fee when you place your order. These units are rebuilt by the same company that rebuilds all of our other injection components including injectors, ecu's, and auxilary air regulators. They've been rebuilding injection parts longer than the Z man has been working on z's which spans over 3 decades. Each of these units is thoroughly tested after rebuilding them and carries a 12 month or 12,000 mile warrantee. Last update 01/07 |
