HKS makes two factory-location R-Type cores for the R32, R33 and R34 GT-R. Here is how they differ and what they mean for fitment.

|---|---|---|---|
| HKS R-Type W600 | 13001-AN007 | 600 x 300.5 x 103 mm | R32 and R33: the factory option fog lamps can't be kept. |
| HKS R-Type W700 | 13001-AN008 | 700 x 304 x 103 mm | R32 and R33: the recirculation pipe and option fog lamps can't be kept. R34: the stock recirculation pipe can't be kept. |
Piping
The cores are sold without piping. The HKS piping kit 13002-AN001 is for the R33 and R34 GT-R. R32 owners, ask us about pipework.
Before you upgrade
Ask your tuner whether your intake temperatures call for a bigger core.
