BOFI Racing Supercharger Intercooler Kit for Mazda MX5 NA NB

The BOFI Racing Supercharger Intercooler Kit for Mazda MX5 NA and NB is the easiest way to add an intercooler to the Salon Motorsport Supercharger kit.

We’ve looked at the modifications we’ve done ourselves over the years and have built a one-size-fits-all system that incorporates provisions for Idle Control Valve, BOV, IAT and a vacuum line, each supplied with a blanking cap if you do not require them.

The intercooler itself is a BOOST Products unit, utilising a tube and fin design for maximum airflow through the intercooler, cast end tanks and a high fin count with internal turbulators – these units are excellent value and far outperform the typical ebay intercooler.

The intercooler mounts support either a 180mm high intercooler or a 230mm, with excellent distance to the radiator as well as fitment against the factor air dam – it fully fills the mouth of the car, yet won’t ruin airflow to the radiator.

On track with an ambient temperature of 18°C, without a cold air feed or an exhaust heat shield, we saw maximum intake temps of 25°C.

The kit includes;

  • Mounting Hardware (M6 nuts & Bolts)
  • 4mm Stainless mounting brackets (compatible with 180cm and 230cm)
  • 10 x Stainless Clamps
  • 6 Pieces of 6mm wall 2.5” ID boost piping
  • 1 swaged aluminium up-pipe with (25mm) takeoff for BOV, IAT (M12 x 1.5), IDLE (19mm) and Map provision and associated blanking caps.
  • 2 swaged aluminium joiners (100mm)
  • 230mm intercooler


*Product displayed for demonstration purposes, final product will be as per specification. Forge BOV sold separately, IAT sensor sold separately, idle hose may be re-used from factory.

If a coolant re-route is installed, the throttle body elbow can be cut up to 35mm for clearance.

*Up pipe is not customisable, blanks are provided for sections not used – you may re-purpose as needed.
