Sprogley Motorsport Enlarged Air Feed for Astra H Mk5

Sprogley Motorsport enlarged CDTI air feed for the Astra H
 
This kit can work with both an open cone filter and our SM CDTI Airboxes.
 
We realise that other CDTI 80mm kits are supplied with the stock CDTI air feed, however this is narrow and could pose a restriction to the rest of the kit. We essentially cut the air feed where the volume is still large and attach our own part that acts as a coupler to correctly attach the 3" ducting. Not only does this insure a perfect and tight fit, but removes a restriction, making the whole kit no less than 3" in diameter.
