Combining the practicality of a hatchback, the fuel efficiency of a 3-cylinder 1.6L engine, and 300 horsepower, the GR Corolla can do it all. Toyota's Gazoo Racing department didn't hold back when they designed the GR Corolla, but they did leave a little room for improvement.----Any time you're pushing 100 HP per cylinder, the engine is going to be producing a lot of heat.

This kit mounts our 14-row dual-pass bar-and-plate oil cooler in the upper grille using direct-fit brackets. This allows more airflow to the cooler and provides a dyno-proven 13-degree average reduction in oil temps. This kit also adds 0.76 quarts of oil to the system, so you can stay on the throttle longer without driving up your oil temps.

Combining the practicality of a hatchback, the fuel efficiency of a 3-cylinder 1.6L engine, and 300 horsepower, the GR Corolla can do it all. Toyota's Gazoo Racing department didn't hold back when they designed the GR Corolla, but they did leave a little room for improvement.----Any time you're pushing 100 HP per cylinder, the engine is going to be producing a lot of heat. For the GR Corolla, that heat rears its head in the form of high oil temperatures.\u003c\/p\u003e\u003cp\u003eThe fast spinning turbo and high 10.5:1 compression ratio means the oiling system is doing a lot of heavy lifting, and that results in oil temps soaring over 260 degrees for some. To help cool the GRC's spunky engine, Mishimoto has developed a performance oil cooler kit fit for the Gazoo Racing spirit.----Our 2023+ GR Corolla oil cooler kit includes everything you need to get your GRC's oil temps under control. This kit mounts our 14-row dual-pass bar-and-plate oil cooler in the upper grille using direct-fit brackets. This allows more airflow to the cooler and provides a dyno-proven 13-degree average reduction in oil temps. This kit also adds 0.76 quarts of oil to the system, so you can stay on the throttle longer without driving up your oil temps.

Each cylinder is running at the limit, and your GRC's cooling system has a lot of work to do to keep up. Long battles on the track or sitting in traffic can easily overwhelm the stock cooling system, and some owners have seen oil temps over 260 degrees on track. The stock oil cooler on the GRC is a liquid-to-liquid design that relies on coolant temperatures to maintain safe oil temps.\u003c\/p\u003e\u003cp\u003eIf your radiator can't keep up, it's only a matter of time before your oil can't either. That's why Mishimoto has developed a performance aluminum radiator to keep every aspect of your GR Corolla's engine cool.----This all-aluminum radiator replaces the stock plastic end tank unit with a core that is 51 percent larger. That increase in core volume means your cooling system can hold more coolant and dissipate more heat, placing less stress on the cooling system overall. Inside the core, we've focused on utilizing the entire cooling area with strutted tubes and louvered fins. Strutted tubes allow us to use a single, wider tube, that has greater effective area than multi-row cores. These strutted tubes also significantly improve core rigidity to help prevent leaks from impacts like potholes or running off track. Louvered external fins circulate air throughout the core to transfer more heat. Finally, the included foam shrouding ensures cool air goes through the core, not just around it.----In addition to performance, we've also thought about durability and serviceability. Our radiator features reinforced intercooler mounts, so you can add a larger intercooler (like Mishimoto's) without worrying about the mounts breaking. To help service your new radiator, we've designed an extended drain port with a slotted drain plug, to keep draining mess-free. Of course, this 2023+ GR Corolla performance radiator is also backed by our Mishimoto Lifetime Warranty for a lifetime of performance.\u003c\/p\u003e\u003cul\u003e\u003cli\u003eFeatures and Benefits 51 percent increase in core volume over stock for improved cooling performance Single-row core with strutted tubes utilizes entire core thickness for cooling Louvered external fins improve heat transfer\u003c\/li\u003e\u003c\/ul\u003e","brand":"Mishimoto","offers":[{"title":"Default Title","offer_id":44314632388659,"sku":"MMRAD-GRC-23","price":638.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/2778\/1939\/files\/990e73abc22ecfea4f3f7af945471647L.jpg?v=1778910482"},{"product_id":"mishimoto-gr-corolla-performance-intercooler","title":"Mishimoto GR Corolla Performance Intercooler","description":"\u003cp\u003eUpgrade your 2023+ Toyota GR Corolla with the Mishimoto Performance Intercooler for a remarkable boost in performance and efficiency.

D4 ATF is a fully-synthetic product designed to satisfy the improved low-temperature requirements which will be in the new Dexron IV specification, and the improved shear-stability requirements which will be part of the new Mercon specifications. D4 ATF also provides a GL-4 level of gear protection, making it a superior product for transmissions and transaxles like the Corvette's T-56. The balanced frictional characteristics provide smooth and consistent shifts for extended drain intervals. The superior stability compared to petroleum ATFs allows high-temperature operation without varnishing valves and clutches which leads to transmission failure.

A higher viscosity compared to conventional Type-F transmission fluids provides higher torque converter efficiency at higher temperatures and the enhanced extreme-pressure protection provides five-times better film strength when compared to petroleum ATFs, reducing gear and clutch wear considerably. This product can also be used in manual transmissions which require ATFs, providing better gear wear and better shiftability, but Red Line MTL® will provide even better wear protection and shift action. \u003cbr\u003e\u003cbr\u003e*C+ ATF* \u003cbr\u003eSatisfies the performance requirements of Chrysler Types 7176 and ATF+4 (Type 9602), while providing 30% greater operating viscosity, 1\/3 the evaporation of petroleum ATFs, and improved oxidation and sludge protection. Red Line C+ ATF provides the exact frictional characteristics required in the Type 7176 specification, providing proper shift feel and proper lockup torque converter operation. The use of an improper fluid could cause torque converter shudder or harsh shifting. Red Line C+ ATF also provides the best low-temperature shiftability in automatic transmissions allowing proper shifting at extremely low temperatures and will flow down to temperatures as low as -60°C. The improved wear protection makes C+ ATF the perfect automatic transmission or transaxle fluid for Chrysler vehicles. \u003cbr\u003e\u003cbr\u003e*High-Temp ATF*\u003cbr\u003ePerfect for heavily-loaded vehicles, this is a synthetic ATF which is a GL-4 gear oil for use where Dexron III or Mercon is recommended. Superior stability allows high-temperature operation without varnishing valves and clutches. Synthetic High-Temp ATF provides the gear protection of a GL-4 gear oil in an ATF and provides a higher viscosity at higher operating temperatures, allowing the transmission to operate at 70°F higher temperature and still provide the optimal shiftability and improved torque converter efficiency. The evaporation characteristics are significantly improved, being twice as good as our Synthetic ATF and five-times better than a petroleum ATF. The improved thermal stability significantly reduces the rapid evaporation of the ATF which can produce a frothing out the filler tube. The balanced frictional characteristics provides smooth and consistent shifts for extended drain intervals. The superior stability compared to petroleum ATFs allows high-temperature operation without varnishing valves and clutches which leads to transmission failure. This product can be used in manual transmissions which require ATFs and will provide much better gear protection than a petroleum ATF; however, MTL® will provide better wear protection and better low-temperature shiftability in most manual transmissions which call for an ATF.
