Perfectly gapped

Shipping was pretty quick for being custom gapped. Made my car run like a dream

They work

I have no idea about the science behind Ruthenium plugs, but they are new and the name sounds cool, so I always grab them. Work perfectly for my needs and the gapping by Ron is always spot on.

Worth the update

Going from OEM to these RGK plugs with the factory gap (0.03). Road tripped right after install and the Fiesta is feeling as efficient as ever.

Products have always been in great shape, Whoosh has been the one stop shop for parts. Support small business.

Quick shipping

Carefully gapped

Measured them and they all were correct. Went from NGK Iridium to Ruthenium, car seems to be running even better!
