Are these pre-gaped ?Ricardo R.Mar 07, 2024
Best Answer:Hi Ricardo, I'm glad to assist you. Yes. It is pre-gapped already (0.04 inches). If your car/truck appears in the vehicle fitment information below (upon selecting the year, make, model, submodel, and engine size), it is a guaranteed fit part. Grab our lowest price for a set and click the link below to buy it later.
