Review on Bosch Automotive 7413 Copper Nickel Spark Plug by Markus Calderon

Revainrating 5 out of 5

Essential for Porsche Boxster

I bought my 2002 about 8 months ago. Recently there was a lag when accelerating. Since I didn't know what kind of spark plugs were installed and what condition they were in, I immediately bought a set of 6 spark plugs. The BERU spark plugs it contained didn't look very worn, but after replacing them with Bosch I put my foot down and off we went! The work took about 2 hours. I went ahead and changed the spark plugs on my brother-in-law's 2001 Boxster. Its NGK spark plugs were a bit burnt. He also says that he runs better.

Pros
  • Ni-Yttrium reinforced electrode
Cons
  • Waiting too long
