I have both systems. JLT on my blown F150 and the RXP on the Edge. Both get the job done. Ive had the PD blower off of the F150 a couple times since installing the JLT system and there is no oil inside the inlet or intake runners. The only down side to the JLT kit is the size I normally drain them at about 2,500 miles. The RXP can will last the 5,000 mile oil change and normally pulls about 8oz of oil and condensation.
