Skunk2 Billet Timing Chain Cover for Honda K20Z3

Skunk2 Timing Chain Cover for Honda K20Z3 Engines

If you run a K20Z3 in a 2006 to 2011 Honda Civic Si or 2006 to 2011 Acura CSX, this Honda K20Z3 chain cover is one of those parts you appreciate the first time you have to service the motor. The Skunk2 K20Z3 timing cover, SKU: SK2-681-05-5311, is Skunk2 Racing’s take on the K series billet chain cover, built around easier access and more control over the chain when you tear the top end down. We run these exact parts on our own cars because nobody likes turning a simple timing job into an oil leak chase.

Skunk2 Racing machines this billet timing chain cover K20Z3 from 6061 billet aluminum. The big deal is the two piece layout. This modular K20Z3 timing cover lets you get to the timing gear area and pull the head without fighting a one piece cover. It also plays nice with engines that have reduced head or deck height. Skunk2 seals the upper to lower interface with an O ring gasket in a machined groove, so your OEM fit K20Z3 timing cover goal stays realistic, not wishful thinking.

You also get an oversized access door for the timing chain tensioner, which means fewer scraped knuckles and less time pulling extra parts just to reset tension. The integrated Skunk2 timing chain guide K20Z3 helps keep the chain from losing its place when you pull cams or lift the head. That matters if you wrench on your car a lot, or if you have ever said, “It was timed when I took it apart, I swear.” Skunk2 also claims about 14 percent weight savings, roughly 10 oz, versus the stock cover, so yes, it’s a lightweight Honda K20Z3 cover, but don’t buy it thinking you’ll feel that on track. Buy it because it’s functional.

It cleans up the bay, too. You get a Skunk2 engraved timing cover up top with “Skunk2 Racing,” and the lower cover gets the “Innovate or Die” etch. If you like subtle OEM vibes, raw machined might look a little loud. If you like showing the engine off, it’s exactly the point.

Features:

• CNC machined 6061 aluminum billet construction
• Two piece modular design for access and serviceability
• About 14 percent lighter than OEM, roughly 10 oz claimed
• Integrated chain guide to help prevent chain misalignment
• Oversized timing chain tensioner access door
• Stainless steel mounting hardware included
• OEM fitment, no modifications required

Finish: raw machined. If you want a performance timing cover K20Z3 that makes timing work less annoying and keeps the chain where it belongs during teardown, this Skunk2 timing cover Civic Si setup does the job.
