Choose Idle Quality:

Milder 114 Lobe Separation- Smoother, More Vacuum- BP8021
Performance 112 Lobe Separation- Medium Choppiness- BP8020
More Aggressive 110 Lobe Separation- Rougher Style Choppy Idle- BP8019

What Is Lobe-Separation Angle? LSA is the distance from the centerline of the intake lobe to the centerline of exhaust lobe.

Tighter lobe separation results in a rougher idle and less idle manifold vacuum but delivers more midrange and peak power. Wider lobe separation resulted in a higher top-end and makes more vacuum but makes less peak power with a less aggressive idle.
