How Often Replace Spark Plugs
I got 10k miles and about to get a Stage 1. Should I replace?... and afterward how often a year? Ive heard some people say once a year for performance cars.
And that it'll help overall performance / efficiency...... |

Every 10K if you have a tune. You should re-gap them to the recommendations of the company that makes the tune you are getting. I have the BMS Stage 1 tune and I have about 4K miles before I'm going to check mine.

Plugs
Quote:
Do you recommend new plugs before JB4 goes or is it okay to put it on? I spoke with JB4 rep and they didn't recommend plugs but I recently read about them on another post. I don't have any issues with my car now, and it runs strong. Would it be okay to but the JB4 on and if I get some misfires, then change the plugs out? I am sure they are stock plugs that have never been changed. My local parts store has NGK performance plugs which come with a factory gap of 0.032 inch. Can anybody confirm if these will fit . Here is the link to the plugs. Im not even sure if these will work. https://www.autozone.com/ignition/pe...lug/444815_0_0 **New to tuning and BMW** |

Yes swap your plugs 2 stages colder to the n20 NGK plugs, gap at .18.
MAKE SURE YOU GAP THEM. Need a part number? Use www.realoem.com Where do you buy them?? Brian Keller at Sun Motors Bmw in PA

I bought mine at the local parts place and used my 15% discount. It was around $54 for 4. I got the required thin wall socket on Amazon for less than $10.

I have had my Stage 1 BMS tune for almost 30k miles and changed them out 15k miles ago. I'm at 78k miles. Your mileage may vary.

I had to replace mine at like 15K, because of carbon build-up and a bunch of misfires. Bought some Autolite AP3923 at AutoZone gapped manually at 0.28 while waiting for the eBay Bosch F5DPORs. Ran with that all the way to 40K.
Then at the 40K service the dealer put back some stockers ($20 per, fyi), which as soon as I got home got replaced with NGK Iridium BKR-7eix. __________________________________________________ ___________ BMW 2500, 2.5 L M30B25 I6 , 3-speed automatic , my old friend All the best,Diceus Last edited by Ortace; 09-26-2018 at 02:41 AM.. |
