Product FAQs
Will this fit a manual GR Supra?
No. This product serves the automatic transmission oil circuit. A manual-transmission model is not an equivalent application.
Why do some 2024 M340i and M440i cars need extra checking?
The cooler arrangement changed with B58N production. A 2024 model-year description alone is insufficient; verify production date and the installed cooler part number.
Must I also buy the 8154 heat exchanger?
No. CSF lists mounting compatibility with both the original heat exchanger and CSF 8154.
