The S54 is an incredible feat of engineering. Smooth power delivery, individual throttle bodies, and an 8,000 rpm redline make for an unforgettable driving experience. As with any BMW, maintaining optimal oil temperatures is key to extending the life of your vehicle and ensuring that you're getting an unparalleled driving experience. As many of these vehicles see frequent track time, the team at Mishimoto decided to develop a performance oil cooler kit that would not only provide improved durability, but also deliver the power needed for track driving. The result: an extremely efficient core that provides a proven 30°F (16.7°C) drop in oil temperature. With an increase in core thickness of 110%, this oil cooler kit increases your oil capacity by 0.44 qt. The oil cooler end tanks, cast from a single piece of aluminum and TIG-welded to the core, have been designed for maximum reliability, giving you the confidence you need to push your E46 M3 to the limits.

This oil cooler kit is designed as a complete bolt-in fit, requiring no modification to work with the stock radiator or the Mishimoto BMW E46 Performance Aluminum Radiator. To ensure a complete direct-fit, Mishimoto engineers have designed a fully CNC-machined 6061 aluminum and 303 stainless steel BMW E46 Oil Line Fitting Kit, which makes the removal of the stock hard lines and installation of stainless steel braided lines a simple task.

This kit includes preassembled stainless steel lines with -10AN fittings to help direct the oil to and from the cooler, as well as a black Mishimoto Oil Line Stay to keep your lines from rubbing. As with all our products, the Mishimoto E46 M3 Oil Cooler Kit includes the Mishimoto Lifetime Warranty

        OG Style
        I am a big fan of Bruno Marc shoes. Over the years they have provided comfortable and affordable boots and shoes. These blue, tan and white soled dress sneakers are no exception. They have a nice finished look that makes them both causal and dressy. The lightweight style is still warm enough for colder mid-west winters. The box of the toes is wide and comfortable. The insole is well padded and a pleasure to wear. This is another fine pair of shoes to add to my collection and yours.

        Must buy: Comfort + Casual + Well Made / Ventilated
        Size: 8, Color: Brown
        Just buy it! I have put in roughly 15,000 steps in this shoes in 10 days and I can't believe how comfortable they are after this much rough use in short amount of time. I highly recommend this shoes to anyone looking for comfort in casual style.

        WIDE Dress Shoes With SUPPORT
        Size: 10.5, Color: Brown
        I've seen dress shoes and worn dress shoes before, but these are simply the best dress shoes I've ever worn my entire life. 99% of dress shoes have the same problem, they have the thinnest little soles that offer no support. BRUNO MARC HAS SOLVED THE PROBLEM. These dress shoes not only support wide feet like mine who historically have had and still have little support in the market, but Bruno Marc has wide options that fit perfectly, and the support with the thick foam sole is so needed and awesome. I had a pleasant surprise putting these things on and there being some tactile grip enhancers inside the shoe so you can feel the shoes better and get a little tickle / massage while you're at it. These things are dripping with style, easy to wear, and while they might look firm on the outside, on the inside the shoe just has such a nice flexibility and foamy feel, the top where the top of your feet feel the roof of the shoe, it has such perfect ooey gooey support I can't believe it. The outside sole also has this neat tactile feel. The durability looks good and feels good for now.

        Perfect Blend of Comfort and Style
        Size: 9, Color: Brown, Size: 9, Color: Brown
        I recently purchased size 9 of these shoes, and they exceeded my expectations in every way! Here’s what I love about them: 1. Comfort: The moment I put them on, I noticed how soft and supportive they felt. The cushioning provides all-day comfort, making them perfect for long walks, workdays, or running errands. 2. Fit: The sizing is spot-on! I ordered my usual size, and they fit perfectly with no need to size up or down. There’s enough room for my toes to move without feeling too loose or tight. 3. Style: These shoes look even better in person. The design is sleek and versatile, making them easy to pair with both casual and semi-formal outfits. I’ve received several compliments already! 4. Durability: I put it on the day of purchase. After wearing them daily for a couple of days, they still look brand new. The stitching and material seem high-quality and built to last. 5. Value for Money: For the price, these shoes deliver exceptional value. You’re getting premium comfort and style without breaking the bank. Final Thoughts: If you’re looking for shoes that offer comfort, style, and durability, I highly recommend giving these a try. I’ll definitely be considering another pair in a different color soon! To conclude, I’m very happy for this purchase. Will definitely buy again.
