1 of 1 people found the following review helpful By N. Termini on May 3, 2014
I changed out the Bosch 4x plugs I had been running in my '98 Ford Explorer (which worked great) after probably close to 100k on them. After less than 6 months, I've noticed a decrease in performance with the OEM plugs from Ford. The idle is rough, cold starts are not as quick, acceleration feels sluggish and gas milage has definitely decreased. After less than 10k on these plugs, I'm thinking it's time to cut my losses and get rid of them even though the change-out is a serious pain in the you-know-where.

I always buy my spark plugs here and never had a problem with them. They are the same ones you get from the dealer or any parts store but a cheaper price.
