purchased a 2000 pontiac firebird with 197,000 miles and it had a hesitation/ stutter on hard acceleration, figured it might need a tune up so I changed the oil and installed the E3.44 plugs and the car runs flawlessly now, better acceleration and no more hesitation/stutter. I was told by my uncle last year to put E3's in my 1984 Harley Davidson Softail and it was a night and day difference in throttle response and fuel mileage, which is why I chose E3 for my firebird. Fantastic product, will purchase again and recommend to friends.
more power, reduced emissions, improved fuel efficiency, longer life, faster starts
