MRP fuel injectors come with a lifetime warranty against manufacturing defects. Please note, the warranty does not cover issues caused by inadequate fuel system maintenance.

We do not offer refunds or credits for price differences outside of the sale period. This policy helps ensure fairness to all customers, regardless of when they purchased.

In-stock injector orders placed by 2pm Central Time on business days ship the same day. The overnight-shipping cutoff is also 2pm Central Time. Orders placed after the cutoff ship the next business day.

Injectors sent to MRP for servicing typically leave our shop within 1–2 business days after arrival. Shipping transit time is additional.
