Oil Cooler

Oil Cooler: Keep Oil Temps In Check When You Ask More Of The Engine

An oil cooler does one job: it pulls heat out of the engine oil so the oil stays in its working temperature window. Oil that runs too hot thins out, loses film strength, and stops protecting bearings and rings the way it should. Track days, towing, forced induction and long high-load pulls all dump more heat into the oil than the factory setup was sized for. Add a cooler, usually mounted in the airstream and plumbed through an adapter or sandwich plate, and the oil sheds that heat before it degrades. Most kits here run oil through a finned core and route it with dedicated lines and fittings.

What ThreePiece Stocks

There are 153 products in this category across 10 brands. Mishimoto is the deepest with 93 items, followed by CSF at 30 and Perrin Performance at 10, then Vibrant, Koyo, GReddy, ISR Performance, HKS, aFe and Sinister Diesel. The current in-stock price range runs from $82 to $2,408 - that reflects what is on the shelf now, not a fixed price.

The range spans light sport coupes to diesel trucks. For example, the Perrin top-mounted kit for the 2015+ Subaru WRX sits mid-range, while the CSF dual cooler kit for the Civic Type R FL5 and the HKS S-Type kit for the GR86 and BRZ sit at the top. Truck buyers can look at the Mishimoto 6.7L Powerstroke kit in black or the same kit in silver. There is also older-platform coverage like the CSF cooler for the 1965-73 and 74-89 Porsche 911/930 Turbo.

How To Choose

The first decision is complete kit versus bare cooler. A full kit includes the lines, adapter and mounting hardware sized for your car, so the work is largely bolt-on. A standalone core is cheaper but expects you to source fittings and plumbing yourself. The second decision is single versus dual core - dual setups like the CSF Type R kit target hard, sustained loads, and they cost more. On diesels, the Mishimoto Powerstroke kits are platform-specific, so match the exact engine and year. Higher price here generally buys more capacity and a more integrated fit, not a better deal.

What Else You Need

Coolers rarely go in alone. Plan for the plumbing: check Fittings (634 in stock) and Adapters (699 in stock) if your kit needs them. Since you will be in the oil system, it is a sensible time to look at Oil Filters, and cars adding cooling capacity often revisit the Radiators too. Browse the full Engine Components section for the rest.

Fitment & Ordering

87 products carry fitment data, with strong coverage for Subaru, BMW, Toyota and Ford across model years from 1965 to 2025. Not every product lists a vehicle, so confirm before you buy.
