Wagner Tuning BMW N54 EVO2 Competition Front Mount Intercooler & 70mm Catless Downpipes Kit for BMW 1M, 135i, 335i/335xi (E82 E88 E90 E91 E92 E93) - SS304 High-Flow Upgrade Package

Wagner EVO2 Charge Cooler and 70 mm De‑Cat Pipe Bundle for E82 E88 E90 E91 E92 E93 N54

Transform your E‑series 3.0 twin turbo with Wagner’s EVO2 Competition charge-air cooler and straight-through 70 mm stainless de‑cat pipes. This high-flow bundle is a proven way to cut intake air temperatures, minimise restriction, improve turbo response and keep power repeatable on spirited road drives and track sessions. Perfect for E82 1M, E82 E88 135i and E90 E91 E92 E93 335i and 335xi running the N54 engine.

We run this hardware on customer cars and the feedback is consistently excellent. Fitment is tidy, pressure drop is markedly reduced and heat soak is kept in check, giving that strong, repeatable pull you want from an N54. If you’re chasing reliability with your performance, this is a go-to setup.
