Nevermind fellas!

So after doing extensive research Bosch and Denso are the only brands that make spark plugs for my year and make. I read on e90post that Denso's were terrible and he had to change them out immediately do to really bad shuddering/sputtering.

I pulled the trigger and bought set of Bosch ZR5TPP33 from TurnerMotorsports and should have them installed very soon.

Will update with pics and review then!
