Spark Plugs for bm3 stage 1 93

335fanatic · 11-02-2020, 01:05 PM

Hey guys,
I'm completely new to tuning and am going to be undertaking this operation by myself. I have indeed searched the forums regarding going one step colder vs staying stock. The problem for me is I'm not entirely sure I'll hit the 75-100hp rule of thumb for going one step colder. I currently have the AWE touring axle back with the non resonated midpipe. I am planning to add a vsrf FMIC, along with the VSRF charge pipes and going stage 1 93 octane maps for my 2015 335 xi. I am hesitant to go one step colder because I have also heard it could be more detrimental than helpful if I do not meet the rule of thumb for the hp gains. Would you guys recommend keeping the stock plugs or going one step colder for this setup? Thanks for the help.

Stock plugs stock gap unless you have problems. Plenty of people run this even with stage 2/2+, pump gas and Exx mixes, myself included. Some people even run them with meth+PS2.

Just read my posts here for changing plugs:

Ya stock plugs would be just fine ran stock plugs on stage 2 with no problem although I did upgrade to NGK plugs with a .022 gap as bm3 recommends. Didn't have a reason to other then just for regular maintenance. Honestly wouldn't be a bad idea just to do it whenever you need to change them just so you never run into any spark blow out problems.
