Best on the market - from my mechanic!
Mechanic at Lexus who installed them was blown away by the price! The perfect spark plugs for my 2008 GX470, very high end. The mechanic said they would help improve gas mileage a bit, they are exactly what the factory recommends, will last a long time, and they will help smooth out the engine as well. Very easy to install as they authenticated to the engine.

Great product, reasonable price.
I put these in my 2006 Toyota Tundra 4.7L V8 after having some misfiring issues. It turned out to be the ignition coil, but these spark plugs are running great and are reasonably priced. Much cheaper than paying for the dealership to replace and they're easy to install.

Great fit and they work.
Used these on a 2009 Toyota Matrix 2.4L AZ-FE, perfect fit, same length, same suggested gap already pre-set from factory.

Right part for the right price!
Each plug came ready to install. Just be sure to torque them in properly.

Just what Toyota suggested for the 06 Tundra. Got a little more pep and milage increased slightly.
