Mate your a star, I've been looking for a maf housing for ages. Will be ordering that tomorrow when I've double checked the diameter of the inlet to my engine. Save me using lots of reducers etc. I've got the green twister kit Whitchurch they had to manufacture as they had no Z4 ones in stock and when it turned up a month later it didn't fit lol. I've kept it so I'm Making it fit. I got these off eBay which I'm going to adapt to work as he wanted £100 for a one off made to measure. The morning holes are an exact fit.Welcome Neil!

I haven't finished it yet though![]()

Just found this on eBayThat's something on my list too. My Ramair is tight up against the original air box feed on the front panel which means it gets everything that comes its way as mine is an "open ended" filter, so a bigger scoop behind the grille should hopefully increase the flow even more. It also sounds nice when you give it a boot full................................

Thanks mate!Hi Neil, and welcome from Cardiff.
Hi,Just a note has the roof motor been relocated to the Boot ? if not then i recommend getting this done as when the drain plugs get blocked the water runs into the casing of the Motor. Also has your z got the Gaptec module fitted ?
I would recommend getting it relocated. It cost me £85 to have it done, prevention is better than the cure £1000 for a new oneHi,
I haven't touched the roof motor so I'm guessing it hasn't moved. Yeah I got the gap tech module and will be fitting it next week once I've finished my stereo project.
