The pink line toward the bottom of the chart is from our intercooler install. The grouping of lines above it are with the ion Performance intake. The MSP's 2.0-liter, T25-boosted four-cylinder pumped out 164.5, 165.1, 165.0 and 166.2 runs in fairly quick succession. Peak power improvements were in the 5- to 6-hp range, but the intake really earned its keep low in the powerband. From 3500 rpm to 5000 rpm, there's a uniform gain of around 17 whp, with the biggest jump hitting at about 4700 rpm where 24 whp was realized.
