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.

Title say it all. Works perfect, every time. No effort required
Amazing quality and craftsmanship. It was customized just like I wanted. Once the car is finished being built I'll add a picture to the review.

2013–2016 Hyundai Genesis Coupe Battery FAQ's
Please read our FAQs page to find out more.
Is a lightweight battery worth it on a track‑driven BK2 Genesis Coupe?
A quality AGM or LiFePO₄ sheds several kilograms from the nose of the 2013–2016 Hyundai Genesis Coupe, improving balance. Ensure adequate cold‑cranking for the Lambda 3.8 V6 (’13–’16) and Theta 2.0T twin‑scroll (’13–’14), use a rigid tie‑down, and add heat shielding near the turbo on 2.0T models.
Can I relocate the battery to the trunk on the BK2 Genesis Coupe?
Yes—use appropriate‑gauge cable with a fused disconnect near the battery, route through grommets, and vent sealed enclosures to the exterior. Secure the tray to solid structure to handle RWD loads.
What electrical checks should follow a battery upgrade on the BK2 Genesis Coupe?
Clean grounds, verify alternator output under load, and confirm idle voltage with lights and blower on. Stable voltage keeps coil energy, injector latency, and pump flow consistent.
