Fuel Injector Installation Note

WARNING: This page is about a different car, the 2020 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

If engine oil is applied to the fuel injector, it could adhere to the injection holes and inhibit the fuel injector function. To prevent this, apply engine oil to the cylinder head side.

Apply engine oil to the fuel injector installation holes.
Insert the fuel injectors to the installation holes one by one, being careful of the direction the fuel injectors are pointed.
