Product Description
99-00 JDM Roadster (Miata) & 04-05 Mazdaspeed Miata intake cam
Drops right into 99-00 BP4W head.
- .349 lift
- 251 degrees duration
This “BP5A” cam has slightly more lift duration than the 99-00 USDM intake cam (.326 lift / 248*). Adding this cam will usually add about 6hp to an otherwise stock 99-00 engine. Fully compatible with the stock ECU. Expect a bit more if you have a header, intake and exhaust. No before/after dyno charts available for this item.
