{"title":"Spool Performance","description":"\u003cp\u003eSpool Performance boost plumbing is grouped here for two very different platforms: the BMW B58 and the Porsche 911 Turbo (992). The collection currently holds a Spool charge pipe upgrade kit that covers both B58 Gen 1 and B58 Gen 2 engines, a turbo inlet pipe for the 992 Turbo, and a set of intercooler boost pipes for the same car.\u003c\/p\u003e\u003cp\u003eThese parts are aimed at owners replacing factory plastic or restrictive piping, usually alongside a tune or other power upgrades where boost pressure climbs. On the B58, a charge pipe swap is a common preventive job before a stock pipe cracks under higher boost. On the 992 Turbo, inlet and boost pipes are fitted as part of a broader intake and intercooler build. Confirm whether your B58 is a Gen 1 or Gen 2 engine before ordering.
