This weighted shift knob makes shifts faster and the extra-large globe shape encourages over-palm shifting. The Black Forest Industries Billet Knob weighs in at 8.8oz (250g), about twice as much as a stock knob and a little heaver than the BMW ZHP knob. The heavier knob amplifies the pendulum motion of the shift lever resulting in smoother and faster shift times. BFI has designed this knob for BMW and VW fitments to fit snug on the shift lever and be secured with Allen set screws. They were careful to reduce tolerances compared to universal knobs. The overall height of the BFI knob is the same as stock anatomic knobs (some BMW M/Performance models have a stock knob that is shorter than this one).

Included with the BFI Billet knob is a matching BFI crest shift emblem. A 5 or 6-speed pattern emblem is available separately.

Choose from soft alcantara or perforated air leather with either a silver or black anodized base.

Have a leak in your A/C system but can't find it? The evaporator allows the refrigerant within the A/C system to lose pressure and cool down, allowing it to transfer that chill to the air coming out of the dash vents. If leaking, the A/C system will lose refrigerant and not function how it should.

The coolant expansion tank in your vehicle gives additional fluid a place to go after expansion and contraction from temperature change. Because it is subjected to such drastic changes on a regular basis, it can often crack or break. You want to keep all the coolant in your vehicle in the cooling system. If your tank has experienced damage such as cracking, nipples breaking off, or mounting point damage, you will need to replace it. This replacement will fit perfectly and provide the same heating and cooling characteristics as an original unit. When replacing, be sure to have some extra coolant. Check ECS Tuning's website for a wide variety of coolants specifically designed for your car. Most German vehicles require specialized coolant. Be sure to pick up the proper coolant when refilling to avoid damage or premature corrosion.
