Important fitment notes

MQB / OPF cars are a minefield of small variations. Best practice: confirm engine generation (EA888 Gen 4 / EA888.4), OPF/GPF presence, and your OEM downpipe connection type before purchase.

May require ECU calibration and can trigger warning lights depending on your setup and local emissions rules.
