Maruha Reinforced Timing Belt · NA / NB Miata
Maruha's reinforced timing belt for B6 and BP Miata engines. After 30 years, the timing belt on any NA and many NB Miatas is well past its replacement interval — a failure means bent valves and a destroyed engine. Maruha's reinforced specification provides additional confidence over a generic OEM-spec belt for engines running aftermarket cams, higher rev limits, or any performance modification that increases valvetrain load.
Specifications:

Reinforced construction — higher load tolerance than standard OEM-spec belts
Designed for B6ZE (1.6L) and BP-ZE (1.8L) engine applications
Correct choice for engines running Maruha cam upgrades or increased rev limits
Direct OEM replacement fit

Fitment: NA Miata 1990–1997 · NB Miata 1998–2005 · B6ZE and BP-ZE engines.
Made in Japan. Authorized Maruha import by Chikara Motorsports — North America's only official Maruha dealer.
