The Koyo XC351111W is a 35-row universal oil cooler built on Koyorad's advanced drawn-cup aluminum core, measuring 11.25 x 11 x 2 inches with a black finish and an embossed header plate. It is meant for engine oil, power steering, transmission, and differential circuits on track, drift, or HPDE cars. Compared with the shorter cores in the same line, the taller 35-row core gives more heat-rejection area for sustained hard laps, and the optimized internal flow path and high-density louvered fins are designed to help. Its two -10 AN ORB ports let you run AN-to-AN adapters or convert to push-lock barb fittings, so you are not locked into one hose style as you would be with a fixed-port cooler.
Because this is a universal core, it has no model-specific bracket or hose kit, so confirm mounting location, airflow, and clearance before you buy, especially for a front-mount or radiator-side install. Plan for a sandwich adapter or remote mounting, check filter clearance, and budget for AN fittings and hoses, since none are included. Search terms this part matches include "35 row oil cooler 11.25 x 11 x 2," "-10AN ORB universal oil cooler," "drawn cup oil cooler for engine oil and transmission," and "AN-10 track oil cooler kit."
No. The cooler ships as the core only. A fan, hoses, adapter fittings, sandwich adapter, and mounting hardware are not included, so you will need to source those separately.
Both ports are -10 AN ORB (O-Ring Boss) with 7/8-14 UNF threads. You will need matching -10 AN fittings or adapters to connect AN hose, or barb fittings if you convert to push-lock hose.
No. It is listed as a universal fit, so there is no model-specific bracket. Confirm mounting space, clearance, and airflow for your vehicle before purchase.
This is a moderate-difficulty install that requires basic hand tools, AN fittings, hose, and a drill for any mounting brackets. Most setups use a sandwich adapter at the oil filter or a remote filter mount, so check that the adapter seats deep in the filter and has clearance before you commit to a layout. Use hoses long enough to avoid sharp bends, keep them clear of exhaust and moving parts, and avoid mounting the cooler directly on top of the engine, where owners on user forums report it can heat-soak the core. If you reuse a cooler from another vehicle, flush it thoroughly with solvent and let it dry before installing it.
