2 of 2 people found the following review helpful:  Good plugs., Amazon Verified Purchase(What's this?) This review is from: Bosch (4458) HGR8DQP Platinum +4 Spark Plug, Pack of 1 (Misc.) My engine runs great with these plugs. I don't notice any performance difference, but these should last a lot longer than the plugs the last mechanic put in. My engine did misfire after installing these, but the problem was worn out plug wires. I installed Bosch wires and the engine purrs now. 1 of 1 people found the following review helpful: 98gmc, Amazon Verified Purchase(What's this?) This review is from: Bosch (4458) HGR8DQP Platinum +4 Spark Plug, Pack of 1 (Misc.) Works great especially these pre-gap plugs..My 98 Safari is 12yrs old just wanted to use the best to pass smog... Beat our main auto supplier..Bosch (4458) HGR8DQP Platinum +4 Spark Plug, Pack of 1 Happily Surprised!, By John Laviolette (Fort Worth, TX United States) - See all my reviews Amazon Verified Purchase(What's this?) This review is from: Bosch (4458) HGR8DQP Platinum +4 Spark Plug, Pack of 1 (Misc.) I installed these in my 1996 Chevy Pickup this weekend and was pleasantly surprised with the improved "smoothness" of my truck's engine. I had OEM ACDelco plugs isntalled previously, and these really improved things. I'm going to buy a set for my Yukon next. |
