The manifold was coated by Swain Coatings.
That is a TWM induction air box to help funnel air to the Webers.
After our trip to the VIR Gold Cup in June, we took the Alfa off the road for some upgrades and repairs. We ported the head, replaced the head gasket, sent the exhaust manifold to Swain Coatings and installed a TWM Induction airbox. We also replaced our intake manifold with a European carburetted version, instead of the Spica unit that we were using with adapter plates. We even redid the PCV system to help evacuate the crankcase at higher RPM.
Next, we’ll be installing a Momo steering wheel and upgrading some of our gauges with Autometer units.
