I got... bosch platinum plus plugs... and you could feel the difference right away with the new plugs. started faster, idled smoother
As for your plugs, bosch is deff the recommended brand, but just about any high quality plug designed for your engine will work fine. (im currently running platinum in mine, and their fine, but lots of people have reported idel issues with them.) The motor was designed around a copper plug, so thats what it should run on best. so bosch copper is deff the way to go.
newer Bosch plugs, cap, rotor (maybe 15k ago)
Recently replaced original spark plug wire set w/new Bosch; wire set, distributor cap, rotor, O2 sensor and Platinum spark plugs
I think that the recommended plug (and original equipment) is probably a Bosch Silver plug, and that is what I would probably stick to if I were you.
the car seems to run really good at the .028 with the bosch plugs
I am at 20,000 miles with my 07 VW GTI that has several modifications including a chip and I am about to change my spark plugs. I have heard many people say that the colder application spark plugs will work better for my car due to the fact that it is chipped. I went to the dealer and purchased the bosch #101-905-631-B spark plugs which the dealer recommends, but I dont know if these plugs are the colder application? Please give me your guys feedback on what plugs I should buy (Part #'s and website that I can purchase them from). I care about my GTI and want it to run the best it possibly can. I appreciate any feedback you guys can give!
Every time I fill up I check my mileage, I could never get great MPG from the FR8DS, but the coppers were way better MPG wise. Throttle response was less as well. The Silbers always looked more sooty during inspections than the coppers. The silver plug will last longer.
Do not use the Silber plugs. Mileage and performance suffers.
I've had nothing but trouble with the Bosch plugs, from their cheap-o line to their IR Fusion line...
