Scaramanga, I get home tomorrow, I will have a look over the weekend and keep you posted. I have something in mind.

Cheers, just got back from a couple of days in Oz, so look forward to hearing what you recommend.

Minor hold-up on doing this, got completely distracted all weekend. Will post once I have it sorted!! I will definitely do this though, will make the engine bay look so much neater.

No worries! In case helpful to get better pricing on the various bolts/etc, let me know if better to buy together.

As long as folk think they increase power, they will always sell!

And whats wrong with a K&N / Green coton type filter? No replacement needed; easy servicing (not sure about more power but it does get you more intake noise).

Nothing wrong with K&N filters IF your engine has a map-sensor inlet, but the S54 has a Bosch airmassmeter/MAF. This WILL eventually clog up from the oil in the K&N filter, and misread. Just a question of time.

I got the engine light on last year, from previous owners using 'very sporty' filters.
cleaned everything up and from now on only dry/paper filters in my car. Engine light out!

It won't if you oil the filter correctly.

I'm afraid the problem is the oil itself.
Obviously K&N tries to tell us different story. Why would they want to sell less?

The problem is very well known in the big world outside this forum.
Some manufacturer's even specifically advices against these filter types, like Opel.
In the Fiat Coupe camp (Bosch Motronic) people tend to use dry "sportfilters" like Apexi etc. Those often highly tuned engines (4-500hp from 2litre) are of course even more sensitive to errors in the Bosch management.

Interesting about your MAFF prob. Its true that K&N have spent quite a bit of time and effort telling us otherwise. They say platinum wire in the sensor is almost microscopic and mostly sealed off if I remember correctly- the pressure needed to remove the oil is not attainable at any speed the car can go at my a very long way. TBH no probs for me so far in the 4 yrs I've had it installed and believe the car sees plenty of action. I've only recently cleaned both my wife Green filter on her Z3 Coupe and the K&N GruppeM on mine, so it will be interesting to see if any problems arise. Just did a 900km round trip with some pretty severe speeds and nothing so far...

Either way I'm rather weary of either manufacturers claims but would trust more people's own experience on this.

Been thinking about one of my favourite mods that was a component of my old TT engine bay (one of the nicest looking engine bays I've seen, if I do say so myself...), namely a tidy up of the nuts and bolts. I replaced all of them after buying a couple of kits, one to replace the stupid plastic clips holding covers in place and the other to replace the nuts and bolts.

Has anyone done anything similar on their M? The likes of Pro-Bolt or Racing Planet UK tend to be popular providers. If so, any pics and an idea of cost?

Thanks!

I still really want to do this, but spend most of my time away from home. Anyone fancy helping me sort this?

Bump, anyone fancy helping out on this?

Bump again, anyone fancy helping with this?

what specifically do you need ????

Hi mate. I'm not at home with my car very often these days, so I've never had the chance to measure and identify all the visible bolts and nuts in the engine bay. If I can get a breakdown of these I was hoping to look online and identify high quality, aesthetically pleasing alternatives! From somewhere like ProBolt for example.
