No, they cant.
They already offer the Thermostatic kit on their page for the RRP price.
They will also tell you they do not stock the Thermostatic plate or offer it separately.
You have to purchase the plate separately for £80 from Mishimoto UK, which still works out £140 cheaper than the kit.
It seems they do not like to let on that it is Mishimoto UK, either that or someone who drop ships directly from them, probably to save upsetting distributors or something - It seems all the stuff they currently have listed are stock they are trying to shift, as they have Coolant Hoses and Silicone Hose kits from £15 for example.
Mine was delivered last week, Next Day Delivery and can confirm it's a great piece of kit.
Agreed but the plate is actually £100.80 with VAT
You can use 'teammishi5' to get 5% off though.
I'll claim the VAT back ^_^
And it's still a cheaper way of doing it.
