Review on πŸ”₯ Pack of 4 Denso U-Groove K16R-U Spark Plugs: Upgrade your Engine Performance by David Miller

Revainrating 5 out of 5

Excellent Replacement Parts OE

Drove 5000 miles with these OE replacement spark plugs in the first generation Scion xB with no problems. The gap dimensions are ok, no adjustment necessary. No platinum/iridium upgrade required. Changing every 30,000 to 50,000 miles is easy and takes no more than 20 minutes.

Pros
  • Ignition Parts
Cons
  • Negative Present
