Spark plug Bosch or Champion

Plugs have been on for almost 4 days. No problems! Idle and runs smoother! HP feels the same!

The part number I have for the Bosch is 4418. There web sire below only goes up to 2000 EV so I don't know if these are the same as the 2001 + EV. I really love these plugs and ran them in my prior Audi A6. Long lasting, great even spark, no gaping. Bosch claims (see web site) increase power. Maybe?

The plugs that came with our cars from the factory were the Bosch FR8LDC.

I swapped plugs last night and so far no more battery light. I am now on the correct bosch supers While I was getting the flashing battery light I was running bosch supers 2 ranges colder.

I have had exellent results and will probably run nothing but them

I've had luck with Bosch Platinum+4, and also Denso Iridium plugs. My advice to you is just stay away from the cheap stuff. Like "Wally's discount Spark plugs." Stock wires do just fine with any plug for your car.

I've run the platinum +4s in my GTI and I haven't had any problems but I haven't found them to feel any different than any other plug.

i've got some bosch silvers...and this happened after about 12k miles and currently (3k miles) later i'm getting similar symptoms as before.

I have a strong opinion in not suggesting the Bosch or the Beru. There is a reason that BOSH is no longer the OE spark plug in VW, Audi, BMW, Mercedes Benz etc., etc... Stick to the NGK, especially in a VR6, NGK has been OE since the intro of the VR6 six months after Bosh failed to produce a plug that would run in these engine during start up. The Bosch had nothing but running problems.

And I tried both the Bosch and the NGK back to back, and the NGK ran far better than the Bosch. The Bosch were terrible in my case.
