Dose this fit a 03 trailblazer with a 4.2?Alan K.Jun 26, 2022
Best Answer:Hi Alan, I'm glad to assist you. It may or not (we do not carry the direct-fit one for your vehicle). PN 558-321 is designed to be used as a replacement for factory GM coil sub-harnesses and connects to any GM LSx coil. It can be used with Holley EFI LS main harnesses or any other factory or aftermarket harnesses that use a factory LS coil sub-harness. Please see the documentation (<a href="https://documents.holley.com/199r11436.pdf" target="_blank">https://documents.holley.com/199r11436.pdf</a>). Click the link below to order this after checking with Holley and confirming this could work. I hope this helps.

Would this fit 2012 Audi A4 Avant?SharonJan 04, 2023
