The E-series N54 and N55 engines are no strangers to oil cooling problems, that's why we developed the MSL Oil Cooler Kits. The higher capacity oil coolers ensures that E-series models equipped with N54 and N55 engines stay cool, even during heated conditions. We strongly advise combining the cooler kit with the MSL Oil Thermostat.

The MSL Oil Cooler Kits for the BMW 1-Series E8x and BMW 3-Series E9x are available as single or twin cooler kits. The twin cooler kit replaces the OEM cooler on the right side of the car and adds an extra cooler on the left side. The kit comes with the 2x Setrab 19 row oil cooler, 2x stainless MSL bracket, 1x Mounting bracket, 1x Oil adapter AN8, and a hose kit (3 hoses). The MSL Oil Thermostat has to be ordered separately.

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). The installation time is approximately 4 hours.

Knowledgeable and helpful
I purchased a new Sony TV and was having a lot of trouble coordinating the settings. After struggling for 1.5 days, I gave up and called the number for Asurion. There was a reasonable wait while I found the "right" tech person, but it was worthwhile. He was knowledgeable and patient. He gave me confidence and we worked together to solve all my issues. At the end he became pressuring, wanted me to buy a monthly gig with them.

They honor their product.
I've been dealing with Asurion for over a decade now. They're my first choice when making a purchase that I know I'm going to have around for a while. Asurion backs its product to the hilt. I purchased a mid-range priced printer about 2 1/2 yrs. ago along with a 3yr. warranty from Asurion to cover any unexpected 'surprises' that might happen to pop up. Fast forward to approximately 3 months ago, when my printer decided that it wanted to start acting up. The print quality was taking a nose dive; colors were beginning to drop out, showing streaks and fading. Clarity and sharpness are virtually gone. I contacted Asurion about the problem. I couldn't have found a nicer rep to deal with. She said not to worry and within minutes had the situation under control. She sent me all the information and pre-paid postage on how to pack and have my unit shipped to their repair facilities. In less than a week my unit was repaired and returned to me. However, this is not the end of the story. Within a few days, my unit was acting up again and doing the same thing it went in for. Again, I got hold of Asurion (Same great service, different girl). We repeated the same process as before, but this time the unit was there about a week longer. When I finally received the unit, I immediately hooked it up and put it through the numbers, testing everything. To be blunt, the print quality was worse than the 1st time it went in for service. After voicing my displeasure (basically having a hissy-fit), I regained my composure and contacted Asurion, again! This time they told me that since their techs were unable to resolve the issue and to not have me waiting any longer than I have already, they're going ahead and refunding the total amount I paid for the unit. Even though it was somewhat of a Pain-in-the-ASS to go through, I couldn't be happier. Within 48 hrs. I had my refund in hand and I turned around and purchased a replacement Printer. Moral to the story, have a contingency plan, Just in case. Check out Asurion: Great customer service - Nice people, very competitive pricing for their products and they honor their word by their actions. Highly recommend Asurion to anyone.
