Thread: Ideas for new air intake tube from MAF to plenum

I have a split in the flexible tube between the mixer and the solid elbow and I am so sick of the LR tubing its not funny - the Commodore one is rubber not plastic so its a much better proposition.

Cheers and thanks

I started with a second hand 80mm mixer and machined it down to a tight fit, about 76mm I believe. The mixer is an obsolete AMOS inline mixer for an EA-ED multipoint, I pick them up off ebay whenever I see one for this particular conversion. I have 3 at the moment if you need one.
All the other fittings are 80mm or near abouts.

Thanks matey - nice size. I will measure mine but I doubt that mine has a 45mm internal diameter. Providing the extra size would still allow enough vacuum to trigger by diaphragms I would love the extra flow size cause on Petrol it did cause it a little (not much) loss.

Cheers
