PLM Header Assembly Hardware Bolts Nuts

These bolts and nuts feel way more solid than the stock pieces I pulled off my B-series, and the slip-fit collector fit was spot-on. Swapped out all the old hardware in under an hour, no stripping or wobble.

The machined nuts in this kit actually torque down smooth instead of fighting me like the old ones did. Everything lined up with the slip-fit collector on my header without any wobble.

Swapped out the rusty factory studs and nuts on my slip-fit header with this kit and everything threaded on clean with no cross-threading. The machined nuts seat nicely against the flange, which fixed the small leak I had at the collector.
