Radium Transmission Filter | 2009+ Nissan GT-R R35 (18-0028)

The GR6 sheds metal into its own oil by design; the question is only what catches it, and how often you pay for the catcher.

Dual-clutch transmissions live on clean fluid, and the R35's GR6 filter is a consumable Nissan expects you to keep buying. The Radium Engineering Transmission Filter ends the cycle: designed specifically for the GR6 in the 2007+ Nissan R35 GT-R, its element is stainless steel wire mesh that cleans and reuses for a lifetime of service instead of hitting the trash at every fluid change. The 40 micron element is pleated for 5 times more surface area than a flat screen, a progressive-disc internal bypass valve works efficiently from stock through heavily modified power, and an OEM-style integrated diffuser spreads oil flow evenly across the whole element. Made in the USA.

What You'll Feel

• One filter for the life of the car: clean it at service time and reinstall
• Longer intervals between filter attention, with 5x the surface area loading slower
• Bypass behavior tuned for reality, working correctly on stock and heavily built GR6s alike
• Even element loading via the integrated diffuser, no dead zones or hot spots

The Details

The bypass valve deserves the attention it rarely gets. Every transmission filter needs one for cold, thick fluid and pressure spikes, but a crude bypass dumps unfiltered oil into the clutch packs whenever it cracks; Radium's progressive disc mechanism opens proportionally, keeping filtration in play across a wider range of conditions, which matters more as clutch pressures rise on tuned cars. The stainless element flips the service economics, since instead of a paper element per fluid change, you solvent-clean the mesh during the same service and reinstall, and on a transmission whose fluid changes are already a line item, deleting the recurring filter cost adds up fast. Swap it in during your next GR6 fluid service using Radium's installation instructions.
