Porsche made a number of substantial upgrades with the 991.2 Turbo. Engine improvements include revised intake ports, larger injectors, higher volume fuel pump, larger turbo compressor wheels and more efficient intercoolers, but the factory intake system remained relatively unchanged allowing the IPD Plenum and Y-Pipe to fit with only minor modifications.
The 991.2 Turbo Plenum upgrade delivers staggering engine power and torque gains that will raise the performance bar of the already potent supercar as well as the hairs on your neck. Horsepower gains are found throughout the entire power band with the bulk of the gains being realized between the 3500-5000 RPM range. Max power gains of 45+ wheel HP come in at 4300 RPM and hold strong all the way to redline. Torque is even more impressive at 60+ in the midrange with a massive torque gains from 3500-5000 RPM.
