Subietech HQ is Oregon’s only fuel injector service center east of the Cascades!

When you send us your fuel injectors for servicing, you receive the full VIP treatment: multiple flow tests, sonic cleaning, and refurbishing with brand new o-rings and filter baskets (if available). A full report of the testing and video is included with your renewed injectors.

If you are a shop or plan on sending several sets of injectors, please contact us for bulk rates! 

Standard cost is $25/injector, $20/each if flow testing and sonic cleaning only.

Fuel injector service (side feed, top feed, or GDI) includes the following:

We inspect for leaks, Ohm test, review spray pattern, pulse operation, and verify flow rate.

We immerse your injectors in an ultrasonic bath while simultaneously pulsing and back flushing them in order to help remove all debris and deposits from inside the injector. The typical result is fuel injectors that work like new!

Injectors are flow tested again to ensure that they are all performing optimally.

We replace all standard injector seals and baskets if possible – please send your injectors as they are, complete with existing seals and baskets.

Injector pintle caps are often in good condition and do not need to be replaced. If you have broken or missing pintle caps we can usually replace them (some injectors have unique caps that may be special order). We will contact you if your pintle cap is defective.

Need it fast? Our injector turnaround time is typically 24 hours.

Mail-in Services

If you would like to mail in your injectors, please print and complete our service form (see below), and ship it to us with your carefully packaged injectors. PLEASE NUMBER EACH INJECTOR WITH ITS CORRESPONDING CYLINDER. We assume no liability for your injectors until they are here in our shop and a confirmation email has been sent to you.

RETURN SHIPPING: All return shipping charges are the responsibility of the customer. Typical return cost for a set of four injectors via USPS Priority Mail to an address in the US with $300 insurance is between $8 and $12. We will e-mail your tracking information to you if you have included an Email address on the service form.
