The ACT Alfa V6 plenum kit, with internal trumpets & ECU holder
We build with a specific alloy flange for either standard , Ferrari 360 or Ferrari 430 throttle bodies, The 430 has a 75mm bolt spacing which suits the Bosch unit
If you don’t require the ECU holder please email your order and we will deduct £25
We recommend that cars are mapped after fitting this plenum.
Before mapping, just by fitting plenum alone on 3 tests with standard and modified cars we have seen over 10 lb ft torque and extra BHP, with mapping up to 25 Lb ft and 18 BHP.
We generally build to order although we carry stock if possible, allow 10 working days.
