Question?
by Anonymous on April 22, 2021
After I replaced all 5 spark plugs & coil packs, MAP sensor, & the PCV Kit (diaphragm, spring, & spring), my car is running like a champ! I know that it's impossible to give all the credit to the spark plugs, but I had the same VW Jetta as I do now (just 2 years older -- it was a 2010. I now have a 2012) & I had a heck of time using different spark plugs back then when I replaced just the coils & plugs. I was running on 1 cylinder at first, then 3, & finally 5 after I re-gapped the problematic ones. Bottom line, I'm very happy with this purchase. These spark plugs were gapped perfectly!
