Are these gapped?Nori H.May 07, 2023
Best Answer:Hi Nori, I'm glad to assist you. No. This particular part number by A Delco is not gapped. Your certified mechanic would calibrate and adjust it for the right gap. That depends on the vehicle application as well. For us to double-check carefully and be accurate on the part you need, please provide the complete information of your vehicle (year, make, model, submodel, and engine size).

Rapidfire Performance Platinum Series Spark Plug, Set Of 6
Marian G Espinoza's Opinion & Thoughts. I would highly Recommend <a href="http://Carparts.com" target="_blank">Carparts.com</a> to everyone in the USA if I could
I highly recommend <a href="http://Carparts.com" target="_blank">Carparts.com</a> for all vehicle needs & parts. These part stores in the towns & cities are highway robbers & charge a arm & a leg & then some, what I am saying all other part stores rip the people off & they don't care if you are on disability or limited income or if you have cancer or anything. <a href="http://Carparts.com" target="_blank">Carparts.com</a> are the best. #1 Carparts.

When they say "guaranteed to fit" it's real! Never had to send anything back. I will always be with Car Parts.
