BMW B46 B48 B58 Mass Air Flow Sensor is essential for optimal engine performance and efficiency. This sensor regulates the amount of fuel delivered to the injectors based on the volume of air entering the intake. A malfunctioning or poorly maintained MAF sensor can lead to decreased engine performance and reduced fuel efficiency. For reliable performance and precise fuel management, replacing a faulty MAF sensor with a high-quality unit from Turner Motorsport is crucial.

In BMW's with the B46 engine, the intake system is partially limited. The bottom portion is lightweight and great for feeding cold air to the intake, but the top portion is excessively restrictive. Working with some of the original equipment, this intake continues to utilize the bottom portion of OE ducting and heat shielding, but replaces the top with a new high flow inverted performance cone filter. Extensive testing showed up to a 10+ HP gain to the wheels and allows for quicker turbo spool speed. Plus, this design gives you a great sound improvement, letting you hear both the intake and the turbo spooling!

Following in the footsteps of the immensely popular and heralded intake for the BMW N55 engine, the next generation of 6 cylinder intake takes the same path to success. Improve upon the factory design by increasing flow via a larger air box and filter element thereby improving throttle response and lessening the strain on the turbocharger for maximum efficiency. While box and filter enlargement and redesign is a major factor in ultimately producing a more  potent intake they are not the only variables in creating a more efficient design either. The devil is in the details which is where Dinan thrives. Coupled with maintaining Dinan's standard practice of utilizing a sealed system to ensure as much cold, outside air as possible is employed Dinan engineers focused their attention on the intake pipe itself where numerous improvements could be made. In factory configuration the intake tube comes complete with baffling and a small helmholtz chamber to reduce unwanted sound. As a byproduct these features also cause a more turbulent air flow path which robs the factory system of potential power. These 2 specific details are diametrically opposed to our intended markets desires so the removal of these features was paramount. Through numerous iterations a carbon fiber intake tube was developed that eliminated flow disruptions and allowed the natural sound of an unimpeded intake tract to sing. All told this thorough methodology of design allows the Dinan carbon fiber cold air intake for the B58 engine to elicit gains of 15 HP and 13 TRQ @ 6000 RPM on a completely stock vehicle. An impressive feat on today's turbocharged engines.   

Not to be outdone by the performance side of the equation the B58 intake also is completely made up of carbon fiber unlike 6 cylinder intakes of the past where a mix of materials was used. Not only is the intake completely carbon construction but the quality of the material has been improved over previous generations as well. While looks are surely important, and this piece has that department covered in spades, the improved construction and coating also guarantees that the appearance of the engine bay with the Dinan intake will not be marred over time. Built to present well, perform well, and last the duration, the Dinan B58 carbon fiber cold air intake is a modification that is a must for any high high performance build.  

Benefits of the Dinan Carbon Fiber High Flow Air Intake for the F22/F23 M240i, F30/F34 340i and F32/F33/F36 440i:

• More Power: +15 HP & +13 lb-ft of torque @ 6000 RPM without additional modifications (13 WHP / 11 WTQ)
• Sportier Sound
• Improved throttle response
• Larger volume air box (30% larger than stock) that completely seals
• 34% increase in filter area (stock: 76.3in², Dinan: 102.1in²) 
• Optimized carbon fiber intake tube 
• Free flowing injection molded Air Mass Meter housing (8% larger then stock)
• Quick and easy installation

K&N's drop-in air intake filter is constructed from cotton gauze material between aluminum mesh - this makes for a long lasting, high performance drop-in intake filter. These are very easy to remove and maintain. Turner Motorsport recommends this as one of the first maintenance/modifications you make to your vehicle after you purchase! 

K&N's drop in air filters allow increased airflow - dirt and particles stick to the oil on these filters, making them more effective than traditional paper filters in terms of protection. Additionally, K&N believes their filters are more efficient than paper filers - this means more oxygen getting into the engine, allowing vaporized fuel to burn more efficiently and increasing horsepower and fuel economy. The best of both worlds!

• Covered by the K&N Million Mile Limited Warranty
• Washable and reusable
• Emissions legal in all 50 states
• Will not void vehicle warranty

The turbocharger coolant line plays a critical role in your vehicle's cooling system, helping to regulate heat and ensure the turbocharger operates efficiently. These lines, which include both inlet and return components, are typically constructed from durable materials such as metal, rubber, or plastic composites.

Over time, repeated heat cycles and aging can cause these lines to degrade, leading to cracks, leaks, and compromised cooling performance. If left unresolved, a failing coolant line can result in engine overheating and potential turbocharger damage. For vehicles with composite plastic lines, replacing them during any removal or maintenance is highly recommended to maintain a secure seal and reliable operation.
