Extract every ounce of cooling efficiency from Koyorad All Aluminium Performance Radiators with a genuine Koyorad Hyper Cap! This Koyorad Hyper Cap withstands an increased valve pressure rating of 1.3kgf/cm2 (1.3 bar) (18.9 psi) (130 kPa) which increases the boiling point of water and relieves high performance engines of excessive heat. A genuine Koyorad Hyper Cap is recommended for use with every Koyorad All Aluminium Performance Radiator (when applicable). This Koyorad Hyper Cap is manufactured in Japan from high quality components to ensure longevity and performance from your Koyorad Racing radiator.
Why is increased Pressure Better?
It’s simple. When water is pressurized, its natural boiling point is increased. Most modern vehicles are equipped with a 0.9 Bar pressure cap. Koyorad’s Hyper Cap is rated at 1.3 Bar which increases the boiling temperature of your coolant to 267.80 degrees Fahrenheit. That is nearly a 56 degree increase over water's normal boiling point. By increasing the boiling point of water, an engine's cooling system will have the added heat capacity, maximizing performance under ever-changing racing conditions.

Bought as a gift. There was a delay in shipping the item due to stock issues but communication was very good throughout with updates concerning dispatch. I was offered a full refund however I was happy to wait. Mirror is exactly as described. My experience with automek was great even with the delay.
Great communication and service 5*
Fitted perfect. Fast delivery and always on hand to answer any questions

Thanks again guys
Fantastic note change from stock & that bit more responsive top end. well worth its money! Cheers Automek
This battery is awesome, lightweight and versatile.
The team at Automek are 2nd to none.
Great weight, feels much better than the oem fn2 shifter and does the job perfectly. Also looks great. Automek supplied and the turn around was fast, great bunch of people and would definitely recommend
Massive difference with new flywheel and stage 3 clutch, car seems more eager to go. Its a heavy setup but after 2 or 3 weeks I was used to it, now I don't even notice it on the daily commute nor on the spirited jaunt to Fort William from East Kilbride. When the mood or need takes me to get up the revs the car feels like it gets there more freely.
Once again Automek works there magic on my car...can't recommend this garage enough...friendly and know there stuff I wouldn't go anywhere else!!!
Supplied and fitted my coilovers at a very competitive price! Top service ❤️
Was wanting to do an oil change at home & needed a genuine Honda Hamp filter. Ordered & chose click & collect. Item was in stock and was notified that it was ready to collect within 15mns of the order! Grabbed it same day. Excellent service. Thanks Automek!
Needed a 5W40 engine oil for my Honda Civic EP3 Type R for a pre track service, contacted these guys to see what was in stock & they had several options on the shelf. Went down to the shop for advance and grabbed the Millers. It was really great to get some guidance on what to go for in person.
Awesome service as per
