Sometimes they work, sometimes they don't. It's an antifouler that cost like $1.50-$2 a piece. Some cars it'll work for but others it won't. I think it'll possibly work if you use two on each side, but it probably won't fit since there isn't there that much room for each side. your best choice will just either buy a tuner, mil eliminators, or make your own.
anyone try this
