Supertech Intake Exhaust Valve Guide Set of 12 for BMW M42 M50 S50 S52 1989-2000 - GDE-BMW-M50-EI-12

If you're diving into the world of performance upgrades, you might want to check out these Valve Guides. These aren’t just any guides; they’re precision-machined from top-notch Manganese Bronze. Trust me, when it comes to enhancing your engine's performance and durability, this material really delivers. I’ve used these with Supertech’s low friction black nitrided valves, and the combo is like peanut butter and jelly for your engine. They work seamlessly together, ensuring you get the most out of your setup.

Now, if you're pushing some serious horsepower, you might want to consider the exhaust valve guides made from a copper alloy. Why? Well, copper has about three times the thermal transfer capability compared to Manganese Bronze. So, if you're running a high-powered engine that really needs to keep its cool, these copper guides are a solid choice.

Here’s the nitty-gritty:

  • Outer Diameter: 12.56mm
  • Material: 6mm Stem Manganese Bronze
  • Position: Intake/Exhaust

These guides are designed to fit a range of BMW models, so if you own one of these beauties, you’re in luck:

  • BMW 318i (1990-1996)
  • BMW 318is (1989-1996)
  • BMW 318ti (1995-1996)
  • BMW 320i (1991-1994)
  • BMW 325i (1991-1995)
  • BMW 325is (1991-1995)
  • BMW 520i (1990-1996)
