NGK7100 G-Power Platinum Spark Plugs ZFR6FGP - 6 PCSNEW

Replaced old plugs with these and every thing seems ok.

These are now my go to spark plugs for all of my vehicles. Like many people, we drive used (most often high-mileage) vehicles, so needed repairs are almost guaranteed. I consider myself a respectable driveway mechanic, but these plugs were a cake walk to replace in my 04 Liberty with the 3.7L V6. Immediate increase in acceleration and fuel mileage. It also got rid of the slow "chugging" at idle and sluggish acceleration. I also replaced the coil packs, although it wasn't a requirement. In short, these are a great purchase option for those that work on their own vehicles.

Engine doesn't run the same as oem. I think the rpms are lower. ??

Either I made a mistake or Amazon’s fitment guide was wrong. These physically fit but were way too hot a heat range and the truck ran badly. A different / proper set and it runs great. Still 5 stars as NKG makes fine plugs and it’s not their fault I got the wrong ones.

Good

Exact fit for my jeep thank you

These are the wrong plugs for a 2002 Liberty. Look under the hood and buy those Copper plugs.Mine says ZFR6F-11G 6987 are the correct ones. Otherwise maybe Miss fire codes on the way.

Plugs were exactly as described...Easy swap

Threw these in my 2007 dodge nitro and what a difference it made so much power to my engine and better gas mileage will definitely buy again
