Now we move on to the intake and exhaust and ensure proper flow through the engine. Please note that WE DO NOT RECOMMEND INDUCTION KITS, unless you have tuned your car extensively and are finding that the standard air intake has become a restriction. Induction kits can work well on turbo engines and larger engines (if supplied with a suitable cold air feed or air box), generally though we'd just recommend for Captur engines you should just fit a sports panel air filter preferably made from cotton.

Sports exhausts increase the flow of air through the engine. But if your exhaust is too large, ie: over 2.5 inches bore, you will lose a great deal of the flow rate and end up sapping power and torque.

Getting a professionally ported and polished head with larger valves can fully maximise your power gains. A good triple plate fast road performance clutch will help to keep that power going where it should. Never skimp or expect the standard clutch to cope. Remaps offer large power gains on all turbo charged cars. On NASP engines the benefits are doubtful. However a remap on a NASP engine will help unleash the potential if you have done a lot of mods. Despite the large cost involved adding forced induction to a NASP engine will give large power gains. It is often easier to add a supercharger than it is to fit a working turbo. It is more challenging to map a turbo as the boost comes on exponentially with revs.

It is simpler to map a supercharger because the boost is correlating to engine speed on a linear curve. To cope with forced induction you will usually need to decrease the engine compression ratio .
