420g vs. the 180g of a stock knob.
These shift knobs feature a precision CNC machined brass core for added weight as well as a white delrin shell for durability, excellent appearance and ‘temperature management’. A heavier shift knob puts the weight towards the end of the shift lever. This increased momentum while shifting gives you a greater mechanical advantage, allowing for a much more positive feeling throw when rowing through the gears. The delrin shell features a cap with an engraved shift pattern. Since these knobs are delrin, it prevents the surface of the shift knob from getting too hot in the summer and too cold in the winter. These shift knobs make a great addition to your Tenth Gen interior!
**Compatible with OEM & Boomba Racing Short Shift lever, or any shift lever with a thread pitch of 10x1.5**

Bought it on Black Friday and just installed it makes shift smother and you really can feel it go into the next gear with this shift knob
I love this part. It is a perfect fit and look for my 2017 Civic Si. I have been very impressed with how comfortable it is when the car has been setting in the sun. It is so much better than a solid metal knob in terms of how hot it feels.
Buy one, I think you will love it.
