These Bosch plugs were much cheaper to buy than the OEM NGK spark plugs and seem to be really good quality plugs. I am not sure how long they will last, It will be interesting to see. These "laser electrode point" style of spark plugs were recommended to me over the conventional type as they are known to last a long time. The package says Iridium plugs last 4 times longer than regular plugs.

This is the first set in my current 1995 Toyota Pickup. So far I’ve felt an increase in horsepower and overall performance. Time will tell the tale.
