Eight Nine 350HP Intercooler Kit for Mazda MX-5 NA NB

£465.26 inc. VAT

This intercooler solution for your boosted Mazda MX-5 NA & NB is designed to suit everything from an M45 supercharger to an EFR turbocharger; this system is plug-and-play and will handle up to a whopping 350hp.

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, BOV, IAT and a MAP line for the Turbo Wastegate, which we’ve tested to give a far more linear throttle and removes most of the rubber banding present in some turbo builds.

The intercooler mounts support a 230mm high intercooler, with optimised distance to the radiator and compatibility with the factory air dam – it fills the mouth of the car yet won’t ruin airflow to the radiator.

And finally, the entire pipe run is 2.5” internal diameter, with 6mm wall thickness silicone hose – we have run these at over 21psi of boost without issue. All the mould angles have been checked to ensure consistent diameter throughout the bends.

The kit includes

Mounting Hardware
Powdercoated mounting bracket
Stainless Clamps
6mm wall 2.5” ID boost piping with Eight Nine branding
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)

Please note

The product will be displayed for demonstration purposes; the final product will be as per specification. The blow Off valve is sold separately, the IAT sensor is sold separately, and the Idle hose may be re-used from the factory.
If a coolant re-route is installed, the throttle body elbow can be cut up to 35mm for clearance.
The intercooler pictured is 180mm in height.
The Up-pipe is not customisable. Blanks are provided for unused sections – you may re-purpose as needed.

The warranty is good for the period stated in the additional info tab from the date of purchase. Mileage warranties are for road use only and proof of mileage is required. Products must be installed by an independent experienced professional mechanic and the suspected defect must be present at the outset. The warranty does not cover damage caused by incorrect installation, failure to comply with the maintenance requirements of the vehicle, processing or otherwise changing the product, ordinary wear and tear, or any other external influences. Warranties are invalid if the product is used for racing, rallying, drifting, track days or any other form of motorsport or competition. Please refer to the manufacturer's own warranty documentation for more information.

Making a warranty claim

Proof of purchase receipt showing the date of purchase, proof of mileage at installation, proof of current mileage and invoice of the work undertaken by an independent experienced professional mechanic must be supplied along with the returned products for a warranty claim to be considered. If your vehicle needs to be used whilst your warranty claim is considered replacement parts from the same manufacturer should be purchased through BOFI Racing. In the event of a successful warranty claim, we will refund the card that was originally used to purchase the replacement parts, in full or in part depending on the nature of the claim. BOFI Racing reserves the right to make full or partial compensation at its sole discretion depending on the condition and mileage use of the returned suspect parts. For example, if you have used the part for several thousand miles before a defect is noticed, only partial compensation may be offered.
