Reviews of Bosch spark plug

Do not use the Silber plugs. Mileage and performance suffers.

I've used nothing but Bosch in my 2L and never ever had any issues.

Anyways, I put in so Bosch Tri-Electrodes and Beru coilpacks. Once I got the APR ECU back the car fired right up. I drove it for a good hour and no misfires!!!

I've had nothing but trouble with the Bosch plugs, from their cheap-o line to their IR Fusion line...

this summer I switched from oem to platinum bosch plugs and just recently took to dealer and had plugs changed as they said the platinum plugs in fsi engine will cause some fuel to not burn properly.

In my B3 Vr6, about 3yrs ago, I swapout the NgKs to Bosch Fusion 4-prones and my mileage went from 17 or so to 32mpgs. My car responded better and better mileage.

i might switch out the plugs again because my buddy got me some freebie bosch plat 4 and i wanna put the bosch single silvers in.

So far we have; Changed to new spark plug wires, distributor cap and rotor and the distributor is not leaking oil, tried two different sets of spark plugs Bosch F6DTC and NGK/RIDIUM BKR6EIX.

I ran them for awhile in my Passat VR6.They did decent.Burned really well actually. I think when I was running them I only got about 23 MPG.

I've been using Bosch FR8LDC in my car for years with good results.
