Near OEM quality at 1/4 cost

Near OEM performance at 25% of the cost! Bosch Quality replaced NGKs/Toyota OEMs. Great value and now the engine is running smoothly! I have seen a slight improvement in my mpg @1mpg overall in mixed driving conditions.

Fairly-priced OEM replacement

Bosch is a pretty reputable brand for car parts. I purchased these because they were fairly priced, came in a four pack, and have a solid reputation. They perform as advertised. Took the old ones out, replaced them with these, torqued them down, continued on with my life.

Didn’t have to gap to install

Fit in my 2015 Mazda 3 with correct gaps right out of the box. No issues so far
