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.

2015–2024 Ford Mustang Ignition FAQ's
Please read our FAQs page to find out more.
Do coil upgrades help the S550 Mustang 5.0L Coyote V8/2.3L EcoBoost?
Healthy OE coils support stock power. With higher cylinder pressure (boost or RPM), upgraded coils and the correct heat‑range plugs with a slightly tighter gap reduce misfire at load.
What plug spec works well on a mildly tuned S550 Mustang?
One step colder than stock and a modestly tighter gap is common as boost/torque rise. Confirm with logs—watch knock and misfire counters, and adjust based on data.
Any wiring reliability tips for the S550 Mustang ignition system?
Maintain clean head/chassis grounds, route looms away from headers or the turbo, and replace brittle connectors. Stable grounds curb random idle wander and misfire.
