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.

2010–2012 Hyundai Genesis Coupe Exhaust FAQ's
Please read our FAQs page to find out more.
What downpipe/over‑pipe/cat‑back setup works on the BK1 Genesis Coupe Theta 2.0T?
A high‑flow downpipe and 2.5–3.0‑inch cat‑back with smooth transitions reduce backpressure and improve turbo response. Retune afterward to manage boost control and maintain knock margin.
What exhaust choices suit the BK1 Genesis Coupe Lambda 3.8 V6 without drone?
Long‑tube headers with high‑flow cats and a resonated cat‑back add top‑end while keeping cabin noise reasonable. A Helmholtz chamber tuned to cruise RPM helps suppress drone.
Any sealing and hardware tips for the BK1 Genesis Coupe exhaust?
Use new multi‑layer gaskets, torque evenly from the center out, and re‑check after heat cycles. Heat‑shield O2 wiring and apply anti‑seize sparingly on studs.
