AS performance tubular manifold for Fiesta ST 180.
Perfect for fast road or race. Best performance when used with stage 3 Fiestas.
The tubular manifold for the Fiesta ST 180 will see best performance gains when used with a stage 3 setup, hybrid or big turbo setups will see the best improvements.
Stage 1 cars - A standard manifold on a Stage 1 Fiesta will perform perfectly, an upgraded manifold on a stage 1 car will see faster turbo spool but will not see a huge improvement over standard.
Stage 2 cars - Higher power cars will see faster turbo spool and some power increase of around 3-5 bhp. This is very hard to prove on a dyno on a stage 2 car.
Stage 3 cars - A tubular manifold is a must have for any stage 3 Fiesta! The standard manifold will be finding it hard to release the air with the manifold pressure not being able to cope with the power. A tubular manifold has a massive increase in air flow which could see big gains compared to standard.
