🔥 Spectra Premium 99358 Heater: Optimal Heating Performance and Reliability Review

My previous heater was clogged even after multiple flushes. Everything was included in this kit. The gaskets included in this kit were difficult to clip on, so I used the OEM gaskets. My r53 is finally warm again!

Looks and functions like the original. It is difficult to attach the supply line, but this is a mini design and not a heater core error. The problem is getting the pipe and core flanges close enough and then installing the clamp - you need three hands.

Works well. Installation is very simple and straightforward, but requires a pair of strong hands. The essentials are easy to connect and can be done in 30 seconds. The top clamp is tricky, I recommend pulling the core out about 1 inch, then you can twist the top coolant line slightly to pinch the lines to the core just enough to catch with the clamp. This is where some strong hands come into play. Play as before, no need to hold the cord in the core while the other pinches and threads the bolt.
