Spark plug Bosch or OEM Subaru

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!!!

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

Now running the Bosch +2 Platinums and my MPG jumped from about 21 to 25! A lot of others will tell you not to mess w/ the platinums but they are doing well for me.

I got... bosch platinum plus plugs... and you could feel the difference right away with the new plugs. started faster, idled smoother

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!

First step, get those Bosch Platinums to a trash can where they belong. Even when I was in Bosch Fuel Injection Training School back in the early 90's, the Bosch Instructors were telling us not to put them in anything unless we wanted to start chasing driveability issues.

I'm a technition with many years under my belt.... and had numerouse out of the box brand new BOSH plugs that upon installing them were dead, not just one but two in the same set, i would then take em out, check gap, and spark test the plug wires and coil, swop them to a diff cylender and bam.. still crap, im not trying to knock them and im not and NGP rep, im speaking from experience

iv had mor problems with a brand new bosh plug then any other plug.. even cheap knock off checker brands...
