Maruha F Cams · NB2 Miata 1.8L VVT
Maruha's F Cam set for the NB2 1.8L VVT engine. Engineered to work with Mazda's own VVT system — which Maruha notes is already doing meaningful variable timing work at factory settings — so the F Cam profile adds duration and lift for more power at the top without compromising the VVT system's low-end contribution. Street reliable and proven.

Power improvement throughout the mid and top-end rev range
Pairs with Maruha adjustable cam gear for exhaust side timing (VVT intake side managed by factory system)
Sold as a set (intake + exhaust)

Fitment: NB2 Miata 2001–2005 · Mazdaspeed Miata · 1.8L BP-ZE VVT engine.
