    • Amazing cost. Easy to install in the Toyota 4 cyl.

Absolutely perfect pricing. Just a few bucks a plug for high Quality Double Platinum. I have no idea how they can make these (and sell them) so cheaply. Great product, worked flawlessly in the Toyota!

    • Installed and engine started

These plugs went in my engine without issues and the engine started. It runs great and I have no complaints about the function. My issues with the plugs are quality control. Four plugs came gapped at different distances from .030 to .050. That I pretty much anticipated and would not rely on factory pre-gaps anyway. More interesting is what appears as a "shearing" of the base electrode during manufacturing which results in a slightly twisted end and some uneven end. This makes for a slightly different gap at one end of the electrode than the other. Fortunately a very thin, long file was able to quickly remove that and make it even again. For the price, they are certainly worth what you get. ... show more
