Quality plugs, run a little tight but hold vacuum and survive engine heat.

Sizes seemed to run a bit tight but that fits well, these are cheap, survive the heat and weather without cracking and they a definetly rubber insteat of PU plugs and they are more durable for it. I can reccomend these vacuum plugs for most applications.
