COSMO RACING Adjustable Fuel Pressure Regulator for Mazda
Beware - Recently a lot of overseas manufacturers have been flooding the
market with sub-standard regulators that look a lot like COSMO Racing's Adjustable Fuel Pressure Regulator. But
that's where the similarity ends. More importantly, these weak, imprecise and
unreliable knock-off regulators can potentially cause serious damage to your engine, by
running it too lean. Protect yourself, and make sure that you are buying a genuine
COSMO Racing Precision Sport Fuel Regulator. The money you saved on the cheap
knock-off will be short-lived when you're replacing your engine.
