Just changed out the OEM VW Bosch spark plugs on my 2.5L VW Golf. Not difficult at all. 28k miles and 5 1/2 yrs. of mostly short tripping. I noticed the engine not running as smooth so I decided not to wait any longer. What a difference w/new NGK (6737) PZFR5Q-11's! Fantastic plugs. IMO, much better than the Bosch's. I highly recommend all 2.5L owners seriously consider these plugs and NOT go past 30K on the original plugs if they're the Bosch's. Could not be more pleased....BTW, used a little
Permatex 81343 Anti-Seize Lubricant &
Permatex 81150 Dielectric Tune-Up Grease. Also, checked the air filter w/10k of use, very clean. I Could easy see this large filter going 30k miles easy. Cheers! Bill
