Drivetrain loss- real world numbers from numerous sources, no BS internet hype
AW4 4WD -29%
AW4 2WD -26%
5SP 4WD -24%
5SP 2WD -21%
These are real world, documented drivetrain loss result numbers for the Jeeps
Do not believe any inflated internet hype or 'rule of thumbs'
Internet BS of 8% manuals and 10% autos drivetrain loss numbers do not apply to these Jeeps.
They use these inflated numbers to stroke their egos. Only believe the facts

-Open element on tube, NO heat shield, shows slight gain vs. stock, 'Hot Air Intake'
-added Heat shield, better, adds +1-2 rwhp
-TB spacer, on both top performers, adds +2-3 rwhp
-I Wish they tested stock intake and box housing with No element, K+N panel element, + cowl duct CAI tube mod
-I Wish they tested with 62mm TB
