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.

2013–2016 Hyundai Genesis Coupe Fuel System FAQ's
Please read our FAQs page to find out more.
What’s a safe fueling path for a tuned BK2 Genesis Coupe 2.0T?
Upgrade the in‑tank pump, verify clean filters, and consider larger injectors with proper regulation. Retune to confirm rail pressure and AFR stability under sustained boost.
Any fueling considerations on the BK2 Genesis Coupe 3.8 V6 with bolt‑ons?
Healthy pump and injectors are typically sufficient for NA bolt‑ons. Log trims at cruise and WOT after intake/exhaust changes to verify fueling and MAF scaling.
Can the BK2 Genesis Coupe run ethanol blends safely?
Ethanol reduces knock but requires more fuel volume. If using blends, add a content sensor, ensure pump/injector headroom, and tune accordingly so trims and pressure stay stable.
