I take it that the 2.2 Vectra air intake is different to an Astra 2.2 :?

I know the veccy C pipe fits the astra well, but can't see it fitting a vec B dunno..

I picked up a cheap dbilas air inlet scoop from ebay,

the differance between the vec c mod and the dbilas scoop is outstanding!

IMHO Its not worth the £110 that Regal want for it tho

If you are handy with basic tool you could
produce something similar with rectangular plastic piping and fittings

as you said you could make your own https://z22se.co.uk/viewtopic.php?t=4077

nicely done!

Did you notice any differances?
power, noise?

Seems beter in the warmer weather but I am one of the few with a 57i kit and no air box so need all the cold air i can get.

Something to ponder over, i have had reservations in the past but could not identify whether it was just atmospherics or warmer air.
Reasoning some days every car ever owned car pulls, and revs better but not this afternoon quite warm but dont know whether it was the the air density and or other criteria.
7.30 ish went quite well, but knowing conditions can change in minutes i am more inclined to think warmer air giving a decrease in performance.

So, some one needs to come up with a fridge or intercooler? to cool the outside air entering the air intake! Primitive or not as long as it does the job.

it has been looked into on various sites, but it's not as easy as it sounds dunno..

fitting an intercooler on a turbo helps because the intake air is hot from the turbo, but it only cools the intake air to near 'air' temp.

similar for the supercharger, the heat created by compressing the intake air gets cooled by a radiator system built into the inlet manifold, but it's still above 'air' temp.

moving the aircon cooling rad to the air intake would reduce the intake temp, but the power lost by running the aircon cancels out the effect :roll:
