{"product_id":"bmw-s58-downpipe-flenspakking-70-mm","title":"BMW S58 Downpipe Flange Gasket 70 mm","description":"\u003cp\u003eAn exhaust without leaks starts with a proper seal. This 70 mm stainless steel flange gasket replaces the gasket on the downpipe flange of the S58 inline-six. You use it when fitting new downpipes, when swapping exhaust parts and when servicing the system already on the car. The BMW OE reference is 18308053348.\u003c\/p\u003e\n\u003ch3\u003ePerformance and construction\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eStainless steel, able to take high exhaust temperatures and repeated heat cycles\u003c\/li\u003e\n\u003cli\u003e70 mm diameter, sized precisely for the downpipe flange on the S58 platform\u003c\/li\u003e\n\u003cli\u003eKeeps the joint sealed, so no exhaust gas escapes past the flange\u003c\/li\u003e\n\u003cli\u003eFits both the Valvetronic downpipes and the factory parts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cp\u003eThis gasket fits the BMW G80 M3, the G82 and G83 M4, the G87 M2 and the F97 X3M and F98 X4M, all with the S58 inline-six. Whenever you take an exhaust part off, fit a new gasket instead of putting the old one back. That is the difference between a joint that stays sealed for years and one that starts blowing after a few thousand kilometres.\u003c\/p\u003e\n\u003ch3\u003eWhat's included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOne or two 70 mm flange gaskets, depending on the set you choose\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eThe gasket drops onto the flange the way the factory one does, so nothing needs adjusting.
