Spark plug NGK or BERU

I personally run NGK without any issues.

these work fantastic.

You can check the forums and it'll say the same thing your asking . It comes down to personal reference ,everyone (including myself ) that I run with in our 3rd gens we run NGK . Just make sure they are dual pronged and gapped correctly and you'll be just fine .

Use NGK iridium and you will have no problems.

I went with NGK iridium's. The "book" says they should be replaced at 100k. I mostly didn't want to have to fight with them at 100k miles to get them out.

I run usually one of 2 brands. Brisk or NGK both iridium. And both are 1 step colder than stock.

Last time I went Bremi coils and NGK Laser Platinum plugs.

Installed the NGK rs7 plugs and it runs fine. I kept them at factory gap, which was, if I remember correctly approximately .028.

I swapped out the oem plugs for Beru rs7 plugs when I went APR stage 2 at ~3k miles. The car ran well. Fast forward to the present with over 18k miles and is20 swap, and I noticed a few stumbles at idle. Nothing major but I figured I'd change them since APR recommends 10-15k mile intervals (visually the Beru plugs looked fine).

I've tried NGK's gaped at .28 twice now once as preventative maint. and again some 20k down the road out of curiosity and both times i'd miss under WOT.
