Returns/Shipping

A sealed intake system for the BMW Z4 M40i (G29) and Toyota GR Supra (A90) with the B58 engine. It replaces the original airbox and intake hose with a heat-shielded airbox, a carbon intake tube and a large washable cotton filter, to feed the turbo with cooler air and less restriction. Choose the version to suit your turbo.

Features

Fully sealed airbox with a heat shield against radiated heat from the exhaust manifold, plus a second air feed so the sealed box does not starve the engine.
Large 7 in airbox leaves room for strut braces.
Carbon intake tube starts at 105 mm (4.1 in) and tapers to the turbo inlet.
Large 105 mm (4.1 in) washable and reusable cotton gauze filter.
Intake system alone gives 15% more airflow; with the do88 turbo inlet for the OE turbo, 23% more.
Optional do88 CNC-machined turbo inlet with 89 mm (3.5 in) hose connection, in versions for the OE turbo or a Pure 800 hybrid turbo.
UV and heat-resistant high-gloss clearcoat.
Louder turbo and diverter valve sound than the original, as the original silencing elements are not used.

Specifications

Part numbers: LF-230-OE (intake system, connects to the OE plastic turbo inlet), LF-230-INL-OE (with do88 turbo inlet for OE turbo), LF-230-INL-P800 (with do88 turbo inlet for Pure 800 turbo).
The do88 turbo inlet has no crankcase heating element, so the car connector is left disconnected. A custom tune is recommended to avoid a check engine light.
Clean the filter about every 20,000 km with a cleaner made for cotton filters.
