They are what they say they are

Nothing much to review here. I’ve been running step colders for a while now, changing them every 15k miles since they’re cheap, easy, and I’m pushing power. Never had an issue with these, they always come gapped properly and are worth the slightly higher cost for the convenience for me. Been through 3 sets of these and gonna keep running them!

As advertised. Great deal for a maintenance item

These were delivered as advertised. Stock engine, no modifications, these spark plugs did not provide any noticeable difference except for the normal benefits of having new spark plugs. These plugs were competently gapped by Whoosh, however the when compared to the factory spark plugs, the electrodes do not have the same reach. This may or may not be a concern depending on your preferences. Would recommend.

Do it for peace of mind

My spark plugs looked clean coming out, but were probably due to be replaced. Adding these and the Whoosh performance coil packs were a simple install and seemed to chill the car from grumbling at idle. Checked the 0.025 pregap was accurate which saves even more hassle.
