Show original supplier description
The TuneMyEuro SFB 6x33 is a set of six 33mm swirl flap blanking plates engineered to address the prevalent swirl flap issue in BMW diesel engines. These blanks are manufactured from a robust, high-temperature-resistant special compound plastic, mirroring the material used in intake manifolds for durability. Each blank is supplied with Viton O-rings, ensuring a reliable seal upon installation. These blanking plates are designed to fit select BMW 6-cylinder models from 2004 (specifically 330d, 525d, 530d, 730d) that meet EURO4 emissions standards and are equipped with a Diesel Particle Filter. Additionally, they are compatible with all BMW diesels featuring the M57 engine produced between 2005 and 2013, including models such as the 325d, 330d, 525d, 530d, 535d, 635d, 730d, X3 3.0d, X5, and X6. If vehicle fitment is uncertain, providing the VIN is recommended for assistance.
