How the Genesis G70 Oil Filter Access Cover Replacement Came to Life

By: PLUGNPLAYCUSTOMS

Genesis G70 oil filter access cover replacement 29121-G9000

This product started the same way a lot of our parts do. One of our long-time clients reached out after losing his factory oil filter access cover on his Genesis G70. He quickly realized that finding a reasonable replacement was not easy.

The OEM cover is easy to damage or lose during oil changes. Once it is gone, the underside of the car stays exposed and replacement options are limited or overpriced. That is when we decided to make our own solution.

We designed the PLUGNPLAYCUSTOMS Oil Filter Access Cover as a direct replacement for the OEM part number 29121-G9000. It bolts into the factory mounting points and restores the original protection without forcing you to replace the entire undertray.

Fitment was a priority. We modeled the cover from the original part to ensure proper alignment and easy installation. Once installed, it looks and functions like the factory piece.

This cover is perfect for anyone who lost theirs, cracked it, or wants a reliable replacement without paying dealer pricing. It is another example of how customer feedback turns into real products at PLUGNPLAYCUSTOMS.

New G70 Bumper Repair Options | PLUGNPLAYCUSTOMS Bumper Guide and Tab Fix

We just added two new products for Genesis G70 owners who are dealing with broken bumper tabs or misaligned corners. These small parts can save a lot of time and money compared to replacing the entire bumper.

The first is our G70 Bumper Guide Repair Kit. It replaces the factory guide piece that sits behind the bumper corner and helps it lock into place. Many G70s develop loose bumper sides over time, especially after minor impacts or repeated removals. Our repair kit brings that tight, factory fitment back.

The second option is our G70 Bumper Tab Fix STL File. This is a digital file you can print yourself if you have access to a 3D printer. It’s designed to replace the small plastic tabs that often snap off near the bumper corners. Perfect for DIY owners or anyone who wants a quick, low-cost fix at home.

Both options were designed from real G70 parts to ensure a perfect fit. Whether you prefer a ready-to-install repair kit or a printable DIY fix, PLUGNPLAYCUSTOMS has you covered.

Why We Created the Genesis G70 AGS/AAF Delete Kit | Solving the U1008 Code for Intake Shroud Installs

We built the PLUGNPLAYCUSTOMS AGS/AAF Delete Kit for the 2019 and newer Genesis G70 after running into a common problem. While testing our upcoming intake shrouds, the car triggered a check engine light with code U1008 every time we disconnected the factory active grille shutters.

The G70 uses two systems at the front of the car: the Active Grille Shutters (AGS) and Active Air Flaps (AAF). These parts open and close to control airflow and cooling. They work well on a stock setup, but they limit airflow when installing performance upgrades like intakes or intercoolers.

When we unplugged the factory motors, the ECU lost communication and threw the U1008 fault. To solve this, we created the PLUGNPLAYCUSTOMS AGS/AAF Delete Kit. It keeps the original factory module connected and sends the same signal the flaps normally provide. This setup prevents warning lights and keeps the ECU fully satisfied.

Installing the kit takes only a few minutes. Mount the OEM module inside our housing, connect it to the factory plug, and secure the harness. You do not need to cut or modify any wires. Once installed, the car runs clean with no fault codes or check engine light.

We designed this kit to work perfectly with the PLUGNPLAYCUSTOMS Intake Shrouds, now available for preorder. It gives you the extra space and airflow you need while keeping your G70’s electronics completely functional.

Got My Headlight Replaced Under Warranty and Found Out Genesis Quietly Updated the Design

I recently noticed moisture starting to build up inside one of my Genesis G70 headlights. At first it just looked like normal fog, but after a few days it wouldn’t clear up. Since the car is still under warranty, I decided to take it in to get checked. The service department confirmed the housing had a small leak and replaced the entire headlight under warranty.

From the outside, the new headlight looks identical to the original one. Same finish, same shape, same part number on the lens. But while I was upgrading my DRLs to the new Purple DRLs from PLUGNPLAYCUSTOMS, I got curious and decided to take a closer look inside the new housing. That’s when I noticed Genesis actually updated the desiccant pack design.

The desiccant pack is that small moisture absorber that twists out from the back of the headlight. It’s easy to miss unless you’re looking for it. The new one uses a different layout and material that’s designed to absorb more humidity and keep condensation from forming inside the housing.

It’s one of those quiet improvements you’d never notice unless you were swapping parts like I was. If you ever see moisture in your headlights, it’s worth having them checked under warranty. And if you’re already replacing them, it’s the perfect time to upgrade your look with PLUGNPLAYCUSTOMS DRLs.

Final Test Results Are In: PLUGNPLAYCUSTOMS Intake Shrouds for the 2022+ Genesis G70

Final Update: Testing Results Are In for Our G70 Intake Shroud (or Snorkel)!

When we first introduced our custom-designed intake shroud (or snorkel) for the 2022 and newer Genesis G70, it was built based on community feedback, real-world frustrations, and the need for more consistent performance during daily driving and spirited runs. Now that development is complete, we put it to the test.

We ran back-to-back JB4 data logs comparing the OEM intake with the new PLUGNPLAYCUSTOMS intake shroud (or snorkel). Testing covered:

  • Heat soak performance (5-minute idle followed by low-speed cruise)
  • 2nd gear pulls (2000 to 6000 RPM)
  • Launch control acceleration (0 to 70 mph)
  • Regular cruising in various ambient conditions

Heat Soak Recovery

Even in hotter conditions (96°F vs 87°F), the PLUGNPLAYCUSTOMS intake shroud (or snorkel) delivered:

  • Lower starting intake air temperatures (IAT)
  • Faster cooldown after heat soak
  • More stable temps during low-speed cruising

The OEM intake remained heat-soaked longer after stops. In contrast, the new shroud returned to normal temps nearly twice as fast.


2nd Gear Pull (2000 to 6000 RPM)

Both setups were tested under the same road and weather conditions.

  • OEM intake: Showed a sharp IAT spike and moderate boost
  • PLUGNPLAYCUSTOMS intake shroud (or snorkel): Maintained lower IAT and smoother, more consistent boost

Cooler air means denser air, which leads to stronger and more efficient combustion. The data proves this upgrade helps your G70 breathe better under load.


Launch Control Acceleration

While our logs did not include GPS speed data to calculate exact 0 to 60 times, we reviewed IAT and boost behavior from a dig.

  • Lower initial IAT with the PLUGNPLAYCUSTOMS intake shroud (or snorkel)
  • Boost ramped up quicker and stayed more consistent

This helps reduce performance loss from heat soak during repeated launches or track use.


Cruising and Daily Driving

Regular driving logs showed a smaller but noticeable improvement in IAT consistency once the car was up to speed. While both setups performed similarly in light driving, the PLUGNPLAYCUSTOMS intake shroud (or snorkel) held steadier temps and recovered faster in stop-and-go traffic.


Final Thoughts

This is the final update on this product. After dozens of logs across real-world scenarios, the results are clear:

  • Faster heat soak recovery
  • Lower IAT under load
  • More stable boost behavior
  • Better cooling at launch

Use code V1SHROUDS to get $50 off the original version used in testing.

Thank you to everyone who voted, tested, and gave feedback throughout this project. Your input helped shape the final design. We are now shifting focus to new product development and we can’t wait to share what’s next.
