Spark plug Bosch or BRISK

The plug they sent me (Bosch #4417 FGR7DQP Platinum +4) runs absolutely fine on my engine, actually it feels better then before, but I just worried if it is indeed not the correct plug, will it do harm to my engine?

The Bosch side fires are an AAN plug that has a removable top. I will probably use those, they worked great with my B5 S4.

I've been using bosch FD5POR aka rs2 plugs. I'm quite pleased with them.

Bosch F5DP0R on a T3/T4 50 trim at 25psi daily. Love it.

I've been running BOSH+ and it feels great!!

I've used Bosch plugs for many years all types and never ever had one single issue.

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

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!

I bought some of those and didn't think much of them tbh. My engine prefers NGKs for some reason. Feels smoother and more eager to rev. I noticed with the F5DPORs a 'welded on' tip which looked a bit weak

After I put them in (I was one of the first in my region to carry them and use them in my own car) I found a significant loss of power. Swapped those puppies out for some Bosch Supers and I was back to where I was before I put the Plats in.
