EXPERT'S ADVICE

"Upgrade the Single Oil Cooler Kit of your BMW 1-Series E8x to a Twin cooler setup with this Twin Cooler Extention Kit E8x. The twin setup is recommended for cars in a very warm climate and cars that will be used on a track.

The Twin Extension kit comes with the 1x Setrab 19 row oil cooler, 1x stainless MSL bracket, 1x Mounting bracket, and a hose kit (1 oil hose).

Note: This item is not ''plug-and-play''. You will need to make some adjustments to the car to fit the bigger oil cooler and bracket. Additional OEM products that you need for the installation are: oil cooler front air duct (left), wheel arch air duct (left), inside wheel arch for the auxiliary cooler (left).

​Installing the twin oil cooler extension on a BMW 1M requires some extra modifications to make the left oil cooler fit into the car. The 1M is equipped with an auxiliary water cooler on the left side of the car. This is the place where the second oil cooler needs to be installed. To make this fit the auxiliary watercooler has to be removed and probably a bigger radiator has to be installed. It will add extra time to the installation process. "

    Perfect fit and high quality.

    Good product, not much to say. The product arrived quickly, looks to be of high quality construction, fit perfectly and took me only a couple of minutes to install. I love it when a product is no frills and delivers as advertised. I've used various filters from K&N before and have always had very good success with them so I will be buying more of these for sure when the time comes.
