New coils and injectors

Spoolin1 · 10-04-2014, 05:43 PM

Hey guys,

Just got my car back from BMW, which I had new injectors and coils installed due to missfires and all was covered under CPO. I also ordered some new stock Bosch plugs and the sparkplug tool off Amazon for $85 thinking that I'd still have missfire issues but to my dismay, the car runs great with the stock plugs still running great at 39k miles now. No missfires at all with my Cobb stage 1+ aggressive tune and I actually tried out the Linear Throttle and it's so much nicer to drive over the Stock Throttle setting. Just wanted to let everyone know my experience with changing out all of the coils and not having to mess with the sparkplugs even with them having 39k miles, I was very surprised that the plugs seem to be holding up well for this long. I'll hold onto the plugs I ordered in the event missfiring rears it's head down the road.

That reminds me... I need to change my plugs AND SOON. Bought the car a 30k, then put another 30k of bolt-ons/meth LOL - No misfires yet.

Go to amazon, they have the best deals there. I asked BMW while my car was there what it would cost to go ahead and replace the plugs since they were doing the other work anyway and they wanted almost $400 to do it. I said, no thank you. LOL
