Will these fit 2003 cadillac deville 4.6 litre fuel injectors

Yes, the GM Genuine Parts 217-1588 Fuel Injector O-Ring Kit with Assorted O-Rings will fit a 2003 Cadillac Deville with a 4.6 liter engine. The kit includes 12 O-rings that are specifically designed for the fuel injectors on this engine. The O-rings in the kit are made of high-quality materials and are designed to provide a leak-free seal. They are also designed to withstand the high temperatures and pressures that are present in the fuel system. If you are replacing the fuel injectors on your 2003 Cadillac Deville, it is important to replace the O-rings as well. This will help to ensure that the fuel system is leak-free and that the injectors operate properly.

Anyone use these on a '06 equinox? for some reason this part # does show as being compatible on amazon or any other site. thanks

Nope, I used these for a 02 Silverado 5.3L
