Vectra C air pipe

MikeS

i purchased a new veccy C pipe from airbox to to TB and i thought i might mention something to help members who are thinking about doing the mod

i would suggest you get an oil catch tank or move the breather hose somewhere else for starters and do the FPR mod concerning the vacuum hose to the inlet manifold

pull out the AIS sensor from the old air pipe then pull out the rubber seal
oki now with the new pipe cut off the hose connector for the cam breather
get a drill or something similar and start widening the hole that use to be for the breather, roughly about a 5m increase in diameter
push the rubber seal for the AIS into your new widened hole
then put the MAF sensor in as well

ps you might have to widen the rubber seal as the hole might be a bit narrower than before - i used the same method as i did to widen the hole, then used washing up liquid and it is a tight fit 🙂

now you got a decent air pipe without creating holes and the freedom of mind knowing no more sludge on tb, i also used a can of wynns carb cleaner and gave the TB and inlet manifold a good going over, might be worth giving the AIS a quick spray whilst it is out as well

then put the MAF sensor in as well

This item is not the MAF sensor. It is the Air Intake Temperature Sensor. Also, we don't have MAF sensors, we have MAP sensors. (Manifold Absolute Pressure)

Just brought the pipe to fit to me astra - dont fit!

JohnnyN

Why not? Its the same pipe that everybody else has on ther Vectra's and Astra's. How is it not fitted?? Is it catching on something?

K70_RAF

Johnny it doesnt fit on the oval connection on the airbox (on an astra) and it is too long, and if i was to be picky is sits too high and rubs on the underneath of the bonnet when on. Ive had to modify it to fit for now but not happy with it.

Bugger! TBH, Jamees was a pig to get on. It kinked in the flexi bit. I think the pipe went onto the air box with a fight but it was okay in the end. Maybe worth enquiring with that chap on here called 'Earl of Barnett'. He could make you up a nice ally pipe with silicone elbows. That would look mint. He does complete kits in most colours. :-)

was in the process of making my own one when i found getting black silicone pipe is a pain and would not be with me in time for trax so ive kinda bodged this on for now and im gonna try and find a solution at a later date i think. Thanks Johnny.
