ISR Performance - Oil Cooler Kit - 350Z G35 VQ35DE

The ISR Performance Oil Cooler Kit is a complete bolt-on oil cooling solution for the VQ35DE-powered Nissan 350Z and Infiniti G35. The kit routes engine oil through a dedicated cooler using 10AN lines and a sandwich plate adapter that retains your factory oil filter location. A solid addition for track-driven, drifted, or boosted VQ35DE builds where oil temps are a real concern.

What It Does

VQ35DE-powered Z33s and G35s are known for running hot oil temps under sustained load, especially on track or with forced induction. This kit installs a sandwich plate between the engine block and the oil filter, routing oil through a dedicated cooler core via 10AN braided lines before returning it to the engine. The factory oil filter mounting is retained so you keep OEM filter compatibility.

Fitment

• 2003-2006 Nissan 350Z (Z33) with VQ35DE
• 2003-2007 Infiniti G35 Coupe (V35) with VQ35DE
• 2003-2006 Infiniti G35 Sedan (V35) with VQ35DE

Not compatible with VQ35HR or VQ35DE Rev-Up engines. The HR (2007+ 350Z, 2007+ G35) has different block geometry and a different filter location. The Rev-Up has the same physical mounting but different oil flow characteristics that may require a different sandwich plate orientation.

What's in the Box

• 1x Oil cooler core
• 1x Oil cooler bracket
• 2x 10AN braided oil lines
• 1x Oil filter sandwich block adapter (M20 thread pitch)
• Mounting hardware

Note: Oil filter is not included. Use any OEM-style filter with M20 threads.
