If your rocker arm rollers have failed, this can lead to extreme camshaft damage, requiring the camshaft to be replaced. Replace your rockers whenever servicing your camshafts or replacing your hydraulic lifters to ensure long-term engine reliability.

If you are running E85 or ethanol mixes in your BMW, you need this kit! This is a complete plug and play kit to install a Bluetooth ethanol sensor in your S55 BMW. This kit replaces the stock fuel lines from the fuel tank to the engine bay with an upgraded -6an E85 compatible fuel line and adds an ethanol sensor and Bluetooth analyzer to monitor your ethanol content. Includes both Bluetooth App & 5v analog output for JB4 or flash tuning. For your fuel line upgrade, choose the option that supports your current configuration. HPFP to the fuel tank: (Stock) This upgrade replaces both stock fuel lines with one upgraded continuous fuel line from the fuel tank to the HPFP and adds the ethanol sensor. Port Injection to the fuel tank: If you are running our port injection kit, this upgrade replaces the stock fuel lines from the tank to the engine bay, integrates the ethanol sensor and then utilizes a Y adapter to supply the HPFP and PI with fuel. Our custom fittings remove those tee's and extra fittings for a cleaner high flow setup. Non-Fuel-It! port injection to fuel tank: Choose this option if you are running a port injection kit that we did not manufacture or sell. This kit includes a longer 18" feedline from the Y to the port injection rail. You then cut the feed line to the length you need and install the included -6an female fitting or -6an female elbow to make the connection to your port injection rail. All of these kits utilize the BMS custom billet aluminum fittings to integrate with the stock fittings so no modifications are needed. *For the BMW F-series JB4 platform connect the white wire to position #16 on the JB4 25 pin harness. Select WMI Ethanol Setup option 1 to enable pin location 15/16 flex fuel input. *These kits are available for off-road use only *Ethanol Sensors don't actually read the ethanol content, the readings are based on the absence of gasoline, so if your fuel is contaminated your ethanol readings may be artificially elevated.

As BMW enthusiasts, we admittedly did not know how to feel when BMW moved to forced induction. We loved the naturally aspirated power that the NA straight six produced, but Pure Turbos has been able to prove time and time again what a forced induction BMW powerplant is capable of putting down. Here at Turner Motorsport, we trust Pure Turbos to meet all of your power desires - after all, there's a reason the majority of the fastest forced induction BMWs on the road are running Pure Turbos. For those in pursuit of the most substantial power upgrades for their 2.0T B46/B48, Pure Turbos has the answer with their Stage 2 turbocharger upgrade. With supporting modifications, this turbocharger is capable of supporting 400+ whp, enough to satisfy most street drivers' ambitions.

This ARP Main Stud Kit is designed to replace BMW part numbers 11128644674 and 11127613127 for the B58; B58A, B58C, B58D engines found in varies BMW chassis One significant advantage of these main studs is their ability to prevent main cap walk, which can occur when the main caps shift or move out of position, potentially causing damage to the engine. In addition, ARP Main Studs can safeguard the threads of your engine block, providing an extra layer of protection against potential damage. When opting for main studs instead of factory bolts, it's important to note that the engine builder should mic the bores. Using studs may require a line hone to ensure proper fitment and alignment. A line hone is a machining process that can be used to resize and reshape the main bearing bores, ensuring that they are perfectly round and concentric. This is crucial for ensuring proper oil clearance and preventing premature bearing wear. By mic'ing the bores and performing a line hone if necessary, engine builders can ensure that the main studs are installed correctly and that the engine will perform reliably and at its best.

With 5150's ARP head stud kit, you can securely tune up the boost on your BMW S63 engine without worrying about the cylinder heads lifting. Specifically designed for the turbocharged V-8 S63 engines found in high-performance models such as F10 M5, F90 M5, F12 M6, F95 X5M, F96 X6M and F13 M6. 201-4702, 201-4703. As you increase the power output of your engine beyond its factory specifications, the head and block may start to separate, causing factory bolts to stretch and fail. Our ARP Head Studs are designed to be stronger than factory bolts, ensuring your race engine stays together even under extreme conditions. Our Custom Age 625+ kit is made from a material with a tensile strength of 260 ksi, substantially higher than the 190 ksi of the ARP 2000 head stud. It's an ideal choice for individuals who want to push the limits of their S63 builds. ARP S63 Head Stud Kit for: M5 F10 2011-2016 M5 F90 2017 M6 F13 2011-2018 X5M F95 2013-2018 X6M F96 2014-2019 ARP2000 Step 1: Tighten to 30 ft-lbs. Step 2: Tighten to 60 ft-lbs.

Don't neglect your motor mounts! Most stock BMW motor mounts are fluid filled and the stiffness of the mount depends on this fluid. But over time the fluid leaks out and the strength of the mount is greatly reduced. A worn motor mount allows the engine to twist and shift around. The harder you're driving the more shift will occur. As the engine is moving around it can contact other parts in the engine bay - usually cooling related. The mechanical fan can hit the radiator; the A/C compressor can hit a radiator hose, the exhaust will flex and may break. Twisting of the engine can also lead to shifting problems as the transmission twists with it. There are countless issues related to worn or compressed motor mounts so don't overlook these as a regular replacement item (every 50,000 miles).

The guide rails in your timing set for your engine keeps everything tracking properly. Because it is made out of a plastic-like material, years of abrasion can wear parts of it away. The chain can get a little loose and cause noise in the chain. Made from the same material and to the exact specifications as the original part, this replacement chain guide rail will keep everything on track and tight.
