JHM-FSIV8IS - JHM Intake Spacers (8mm thick) for B7 RS4 FSI V8
PROUDLY MADE IN THE U.S.A
Introducing the JHM B7 RS4 V8 FSI intake spacers. They are 8mm thick and CNC machined out of high quality materials.
What do they do? They help bring your intake temps down by insulating the intake manifold from the heat coming from the cylinder heads due to combustion and lengthen your intake runners which in turn creates more torque. With a cooler intake manifold you create a cooler and denser intake charge which helps add more tq and hp, gear after gear! All in all a great mod for the money especially on the RS4 that is lacking in the torque department. With our in house testing we found a gain everywhere in the rev range from 2500 rpm to 8000 rpm. The biggest gains were from 4000 to 6000 rpm, with the 2nd best area of gains from 5000 to 7000 rpm. This was done with acceleration rate calculations in 3rd gear from logs. The BEST part is that we saw that the car didn't slow down after repeated pulls due to an extremely heat soaked intake manifold bringing the intake temps up. Bottom line, the longer we beat on it the better it performed vs. the tests without the spacers.
Fitment: 4.2L 32v FSI (4 valve per cylinder) V8 in the B7 RS4
2 -JHM intake spacers (1 for each side of the intake)
2 - OEM Intake gaskets (1 for the each of the top sides of the spacers that mates to the intake manifold, you can reuse the stock gasket between the spacer and the cylinder head.)- Lower mileage cars only. If in doubt on the condition of your OEM gaskets select the option below for a second pair of gaskets.
10 -longer stainless steel bolts (5 for each side of the intake)
10 - washers for the supplied longer bolts (5 for each side of the intake)
