The 2096/41021 combo is great on the P5. This is my go to setup when going to any track and very rarely stray away from it because it works so well. Good torque from the bottom with good rpm up top, also get good runtime.

The 9886 and the 41019C is another combo made in heaven Lol. This combo is very crisp punchy power that will run your rpms as high as the motor will go. I typically run this combo on road only as the punchyness can get you in trouble with lower traction.

Some may be wondering what the 41019C header is and its simply a conical version of the 41019.

Right now I'm running the Novarossi CLIO P5 with the 2096 Super Strong and 41021 header. I usually run the 6.5 restrictor and a C6TGC plug. I always start here and very rarely change from it.
