CZP Cooler Kits are Built to Order and Ship in 3-5 days
The CZP Oil Cooler Kits are essential for any VQ35DE, VQ35DE Rev-Up or VQ35HR equipped car that's going to see track time, abusive driving conditions, or boost. The VQ35 especially is known for running excessively hot oil temperatures, which will cause engine wear and even keep you grounded. Our oil cooler kits add full-flow oil cooling; arguably the best possible solution for keeping oil temps in check. With a variety of options including flow type, core size, and line type, these kits can be built to suit a mild street car as well as dedicated track cars!

Concept Z Performance 350Z G35 Engine Oil Cooler Kits fit all Nissan 350Z Z33, Infiniti G35 Coupe and 2003-06 Sedan models equipped with a VQ35DE, VQ35DE Rev-Up or VQ35HR models including Nismo, turbocharged, and even supercharged equipped cars. Some applications may require extra steps related to the oil line routing or core mounting not covered in the instructions.

The CZP Oil Cooler Kit comes complete with all necessary components as well as instructions with pictures for an easy installation.

These components include:

• 1x Mocal HD Oil Cooler Core (19, 25 and 34 row cores available)
• 2x Mocal -10 AN to 22mm Port adapter fittings (for cooler core to AN lines)
• 1x Mocal Sandwich Plate (thermostatic and non-thermostatic versions available)
• 2x Mocal -10AN to 1/2in BSP adapter fittings (for the sandwich plate to AN lines)
• 2x Dowty Seal 1/2in BSP (for Mocal sandwich plate fittings)
• 1x CZP Universal Oil Cooler Lower Bracket
• 1x CZP Z33/V35 Oil Cooler Upper Brackets (long and short)
• 1x CZP -10 AN SS Oil Cooler Line Set (Optional FireFlex protective sleeving available)
• 1x CZP 350Z/G35 Oil Cooler Install Hardware Kit

What core size do you need?
The Mocal HD cores sizes offered are 19 Row (13" x 1 1/4" x 5 1/3"), 25 Row (13" x 1 1/4" x 7 1/2"), & 34 Row (13" x 1 1/4" x 10 1/4").
The 19 row oil cooler is great for a naturally-aspirated car that occasionally sees spirited driving or even the occasional track day. For forced-induction applications, we would highly recommend stepping up to one of the 25 or 34 row cores, the latter being a great choice for cars that really need the extra cooling capacity, but the size of the 34-row does sometimes limit your ability to run certain air intakes or other heat exchangers.

Thermostatic or Non-Thermostatic Sandwich Adapter?
The Mocal sandwich plates used in the CZP Oil Cooler kit are available in both standard full-flow and thermostatic versions. We recommend the thermostatic versions for street-driven vehicles, as these allow the engine oil to reach operating temperature and maintain it through almost all driving conditions. In general, the full-flow (non-thermostatic) version is recommended for track-only cars that need the most oil flow possible through the cooling core.

Protected -10 AN Stainless Steel Lines?
Silicone-jacketed fiberglass sleeves by Fireflex resist abrasion, heat and oil/moisture common to engine bays and cars in general. These sleeves are a great way to protect the oil lines from hot components in the engine bay on track cars, or anyone looking to go the extra mile to clean up their engine bay.

Please note: Non-Thermostatic Sandwich plates have switched to a new M22 fitting which does not require or include dowty seals, and this is indicated by the (22) stamp between the fittings on the sandwich plate. This change is inconsequential and actually simplifies installation, but we wanted you to be aware of the change nonetheless.
