The aFe Momentum GT intake for the 3.4L twin-turbo V6 uses two sealed one-piece XLPE housings, each with a clear sight window, and two dyno-tuned XLPE tubes. Each side carries an 8 in tall Pro 5R filter with a 3 in flange and five progressively finer layers of oiled cotton gauze behind expanded metal impact protection. Together they flow 525 CFM @ 7 in H2O, 18% more than the factory intake, for gains of up to 21 HP. Optional silicone plugs close off the housings to block hot engine-bay air and reduce intake noise.
