Some may say they are only valve stem caps, but honestly…they are far more. The quality from JD Customs is everything people have been talking about. Decided to dip my toe into the burnt titanium water that JDC offers, and now I’m buying a snorkel. This certainly will not be my last purchase.
These look much better than the stainless bolts that come on Airlift struts and hold tight after use. A great upgrade!
Work of art! It’s actually kind of breathtaking when you open the box.
Thank you Paul, for helping me put with this badge. This badge looks amazing and I love it underneath of my Subaru Sti.
Absolutely perfect in every way possible definitely a perfect touch to the controller
As always you guys killed it with the design and quality and customer service delivery was super quick what else can I say other then I love everything I’ve gotten from JDC
The power steering cap is a must-have piece for your Mitsubishi. The quality of the lettering and etching is incredible. And shout out to the team who color the parts. I wanted a bare background and burnt lettering so that it would match my engine bay theme and colors. They typically don’t do that, but they went out of their way to laser etch around the burnt lettering on top and polish the sides to remove the burnt coloring. They did this for all of my other parts too! I can’t thank y'all enough! I highly recommend JDC’s products!
It’s beautiful 😍, I’d buy it over and over, JDC always with the best titanium parts and ideas.

Mitsubishi Evo X (CZ4A) Engine Components FAQ's
Please read our FAQs page to find out more.
What internal upgrades are common for higher-boost Evo X builds?
Forged pistons and rods, performance bearings, and ARP head studs are typical past basic bolt-ons. Pair with cams and valve springs for sustained high RPM.
Does the 4B11T benefit from a head gasket upgrade on the Evo X?
For elevated boost or frequent track use, an MLS gasket with proper surface prep and torque helps maintain sealing and reliability.
Are aftermarket camshafts worthwhile on the Evo X?
Stage 1–2 cams improve top-end flow and powerband width. Degree the cams and retune for MIVEC targets and idle quality.
