Does this have the right dimensions for the engine review said they don't fit?Marcus G.Mar 17, 2022
Best Answer:Hi Marcus, I'm pleased to assist you. The customer who wrote that review may not have properly entered the complete vehicle information before he/she ordered this set. These are direct-fit OE (Original Equipment) stock replacements. You'll have to enter the year, make, model, submodel, and engine size (very important) as this set is part/s of the engine. Click on the link below to check. If our system guarantees the fitment, you can go ahead and order at 48% off the regular price today while supplies last. I hope this is helpful.
