Supertech Forged Pistons for Mazda MX-5 NA NB 1.6

Supertech Forged Pistons for Mazda MX-5 NA NB 1.6

Supertech draw on over 40 years experience in the design and manufacture of racing pistons. The latest CAD and analysis software enables Supertech to design strong, lightweight high-performance pistons. Manufactured from 4032 high silicon alloy that resists thermal expansion and wear. Thanks to the exceptional thermal conductivity, Supertech pistons have been tested up to 42psi of boost with alcohol.

Supertech’s 2 or 3 step forging process produces a fine structural grain. The material fibres are orientated in the same direction as stress to provide an exceptionally strong piston. Coupled with heat treatments, Supertech pistons have extremely high tensile strength.

Each piston undergoes several steps of machining to ensure it is dimensionally perfect. All pistons feature reduction grooves to reduce contact with the cylinder wall. Pin bores are honed and reamed to provide a precision fit with the high-strength wrist pin, which is used in conjunction with wire clip locks.

Supertech pistons benefit from a phosphate dry lubricant coating to improve lubrication of the skirt and cylinder wall. The coating also prevents micro-welding of the piston ring to the ring land which prevents the ring rotating in the bore and increasing friction.

Warranty information

Warranties cover defects in materials and workmanship only. Warranty is for replacement of a similar product, repair of the original product or refund of the purchase value only and excludes all labour and incurred charges including towing, fitting, inconvenience, and purchases of other manufacturer's products. 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.
