Got my 01 CL S yesterday by e30cabrio

09 TL SH AWD 3.7 intake manifold installed, power is increased.

6-14-2009

VSA delete gets an obstruction out of the way (VSA TB) making the 71mm TB able to fully flow especially important for me now that I have an 80mm intake tract.

Coolant bypass gets hot coolant out of the TB (it ran through both the VSA TB & the TB.

The logic there is cooler air in the intake is denser and better for the production of power.

Thanks

Looks really bad like this and I am not taking the rail off because then the cables for the coil packs will be flopping around & touching the valve cover.

P2R pioneered the mod, I am just an early adopter.
