Review on NGK (6737) PZFR5Q-11 Laser Platinum Spark Plug: Long-lasting Performance in a Pack of 1 by Bryan Ramirez

Just installed them on my 2009 Volkswagen Jetta 2.5L with 85,000 miles. With new ignition coils and spark plugs, the idle is much smoother. It ran rough when idling and is now very quiet. Didn't write any codes on the dash. Revain also seems to have the best price. Happy shopping if you need it. The dealer charged 230 for new spark plugs and installation. Lots of DIY guides online to help you remove the engine cover and air intake more easily. Hope that helps.
