Hi,

Please could you confirm the External Torx size needed to remove the ignition coils on the B58.

Thanks.

I’ve got a couple questions, and sorry for my ignorance as I’m not too experienced with plugs, but I have to replace mine towards the end of the year for the 4 year service or before Jan 2021 on the iDrive..

I have a 2016 M135i so N55 - the ones on your website the NGK for N55 say they are colder 2 step plugs. What are the benefits of colder plugs over standard plugs from BMW (other than the cost)?

My car is totally standard right now as it’s within warranty for another year, but I have been thinking about upgrading the intercooler, sports cat and going for MHD/BM3, aiming for a reliable 380-400bhp.
However this will happen likely towards the end of this year/next year when I get the car in for a major service, just had a standard in between oil and filter done recently.

So my other question regarding the plugs are will they be fine for a stock car?
What differences are there if any? Will it be minimal difference stock, and only make a difference if the car is mapped and the parameters of the engine are changed?
When I’m ready to, I’d rather just purchase plugs once and not have to worry if I choose not to map it, but would be benefit if it can run both stock and mapped with no issues.

Sorry again if it’s a silly question, but just want to seek a bit more knowledge and understanding.

I'll need to re-word the website, they're only 1 step colder for n55, 2 steps colder on n55. Thanks for that.

The heat range is the operating range of the spark plug.
With a tuned car that has increased boost or more ignition advance you would normally see higher cylinder pressures and temperatures.

A colder operating plug is to try a reduce the temperature a bit and prevent the plug from melting in worst case scenario.

A higher cylinder temperature can cause 'knock', when the ecu senses knock it will retard ignition to save the engine, which would reduce power. Or worst case you crack a piston/rod.

If your just driving to the shops and back or a gentle commute I would stick with standard heat range. If the car is driven hard and/or mapped then cooler plugs can help.

I have a 16' plate M135i. I run standard plugs as it is my daily although in the summer, I do run MHD stage 1 with an intercooler and all the other goodies in my signature.

As it is my daily and I do a good amount of pootling around, I decided not to go for a cooler plug because you run the risk of carbon build up on the plug. I don't think I have read a single instance of any mildly modded N55 melting plugs so it isn't something I have worried about. I do push mine quite hard when appropriate though. If it was purely a track car, then I would probably go 1 step cooler as it would be getting ragged a much higher % of its life.

Have you logged your Stage 1 map to see if you are pulling any timing?

My last M135i with MHD Stage 1 was pulling 3-6 degrees of timing at WOT which isn’t ideal. I went for colder plugs and lowered the gap which reduced the timing pull close to zero.

Yes when I first mapped it I was having issues with pulled timing but I think it was just adapting itself. That was with a 95map on 95 fuel. It sorted itself out but then I switched to running 99 fuel on the 98 map and it is perfect. No timing changes. This was all on standard plugs that had done 28k miles. They were changed recently but the timing issues were all in the first couple of days after mapping and were fine for months.

I’ve only ever run my car on Tesco Momentum 99 or Shell V Power, so I’m guessing I shouldn’t have this issue should I remap and run OEM plugs?

It might still do it at the beginning. It is a good idea to log your first runs with MHD to make sure it's all ok.

Just FYI, some timing corrections are totally fine. I got worried originally but you aren't going to damage anything. Corrections are the engine protecting itself from knocking and engines can take quite a bit of knock abuse before any damage will happen.

One of the biggest benefits of MHD is being able to log and check stuff yourself rather than a tuner just telling you it's all ok. You get to learn about lots of different things.

I've sometimes had more timing corrections stock than on mhd.
