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.

Great Value on Vacuum caps

Needed a few vacuum caps to plug off an intake manifold. These fit the bill perfectly and a whole assortment was less than one cap from BMW- great value and now I have spares for other projects on hand. We will see how they hold up over time but I am happy with the initial quality they fit tightly and will not leak.
