A definite improvement over the OEM Bosch plugs, I actually had to turn down the idle speed. Performance is also improved. I have used NGK for over 40 years both domestic and competition. Never let me down.

After my research I found that without adding a new ignition system there is nothing better for your car than the original sparks, these are exactly what they say and are identicle to what will come out (accept these are obviously band new), they are pre-gapped so you shouldn't have to make any adjustments just a 14mm spark plug spanner and a 10mm socket the jobs done, excellent. Seller is excellent.
