This isn’t just an aesthetic upgrade. SPE redesigned the venting on the S550 degas bottle for safety: the cap/vent setup is intended to vent out the side in over-pressurizing situations instead of spraying the bay (and yes, coolant/glycol being flammable is part of why that matters). It’s also a bolt-on billet upgrade that uses factory mounting points, retains factory hoses, and seals with an O-ring. Kit includes the fittings, hose ends, hardware, and O-rings.
