🔥 NGK 4589 Iridium Plug: Unbeatable Performance and Longevity! Review

I bought a used 2007 Camry Hybrid and first replaced the spark plugs on these bad boys. All connectors were correctly installed with a pitch of 0.040. Changes were noted immediately. The engine ran smoother and the noise was gone. Very happy with this product!

I bought it for 120,000 miles 2007 Toyota-Camry 4 cylinder. R&R old hit by a gap in the old. Throttle response improved and fuel economy increased from 24 to 26 in mixed mode, mostly around town. I got almost 34 mpg in 1400 round trips, fully loaded, with cruise control.

. When I got it I checked everything between 042 and 044 while my truck called the 032 room. No big deal, just had to push her down a bit. Well done and working. I hope to get 100,000 of them.

Just installed it today. The car drives better. Not sure about durability yet, but from what I've read NGKs are good. The only thing that bothered me was the way they were delivered. They were shipped individually in a box with 5 liters of oil and a heavy oil filter. When I opened the box, 3 of the 6 spark plugs rolled freely in their boxes.

Damn those iridium candles last forever. I pulled my originals 110,000 miles and they looked like new and were in the gap. My son had 156k when he checked them out last month and they looked like new too. His numbers were at the top of the gap, so he rebuilt them and put them back in his 2005 Toyota Sequoia V8. My 2005 Highlander V6 takes over 4 hours to fit the rear 3 so there's no way I'm going to fit new ones.
