Thank you for the enquiry. I am assuming your wrex is a 2L. The 2.5s do not have the cap neck.

The Spec V Radiator for the GD has been on the market for the last 3yrs and the GD ones have not been stocked by the National distributor. In the case of the GD, there are no clearance issues, so the 53mm is recommended.

However, should you require the V series, I can get one flown in from Japan at $560. The air freight from Japan is very costly for bulky items.

Cheers
