Frequently Asked Questions

How much does fuel injector cleaning cost?
$30 per injector for standard MPFI top-feed, $35 for everything else (side feed, GDI, TBI, marine). Round-trip USPS shipping is a flat $15 and a 4-injector minimum applies. A typical 4-cylinder set is $135 total. Optional shipping insurance is available at $2 per $100 declared (USPS already includes $100 of coverage by default).
Is it cheaper to clean or replace fuel injectors?
Almost always cheaper to clean. New injectors run anywhere from $50–$200+ each depending on the application, and that's before labor if you're having a shop install them. A full set of 4 cleaned by us starts at $135 total. Professional cleaning is the smart first step. If flow testing shows an injector can't be restored, then you replace just that one.
What's included in a fuel injector cleaning service?
Everything. Ultrasonic cleaning, backflushing, before-and-after flow testing (static and dynamic), leak testing, spray pattern inspection, new O-rings and micro-filter baskets (where available), and a detailed Injector Performance Report. Round-trip USPS shipping is $15 flat. Optional insurance available at $2 per $100 declared.
Is professional ultrasonic cleaning better than fuel additive cleaners?
They're not even in the same category. Fuel additives can help with light surface deposits if you use them regularly, but they can't reach hardened buildup inside the nozzle or pintle area. Ultrasonic cleaning physically breaks apart deposits using cavitation: microscopic bubbles that implode on every surface of the injector. If your injectors are actually dirty enough to cause symptoms, a $10 bottle from the auto parts store isn't going to fix it.
