## Description (the store's own text)

This oil cooler kit is a high quality accessory designed to help the Honda Grom and Monkey 125 (2021 and older models only) horizontal engine run cooler. Air-cooled engines run hotter when modified (i.e. big bore kits) and/or subjected to heavy loads such as racing use. This kit will help the engine’s durability and reliability by circulating the engine oil through a cooler reducing the engine’s oil temperature.

*Meets or Exceeds OEM Specifications.*

**Key Features:**

- Lightweight aluminum 4 row oil cooler (not a 3 row as many others sell).
- AN fittings
- Crimped, braided lines that are of much better quality then cheap rubber lines or hose clamps that can slip off

**Application:**

- Grom - 2014-2021
- Monkey - 2014-2021

**Note:**

1. Not for stock cylinder
2. This oil cooler must be used with our big bore kit or one that has similar cylinder fittings (Kitaco and possibly others).
3. Tighten banjo bolts to 6ft-lbs
