Review on NGK 6441 ZFR6FIX 11 Iridium Spark by Devin Henry

Revainrating 5 out of 5

You get what you pay for.

Good long lasting spark plugs. I replaced a set of these with 158,000 miles on my 2001 Honda Civic, the car still ran fine, they were just worn out. NGK is very familiar with Japanese cars. Highly recommended.

Pros
  • Longer insulator nose prevents clogging, corrugated insulator ribs prevent burnout and triple sealing prevents leakage of combustion products
Cons
  • 0
