Frequently Asked Questions
Is the 300028 the full PCV cover or just the cap?
The 300028 is the cap only. The Official Billet Technology PCV Cover body is a separate product and must be purchased separately. The 300028 is designed to complete the look of that cover.
Does the 300028 PCV cap fit all 392 HEMI vehicles?
The 300028 fits 6.4L 392 HEMI applications including the Dodge Challenger SRT8/SRT 392/R/T Scat Pack/T/A 392, Dodge Charger SRT8/SRT 392/R/T Scat Pack, Chrysler 300 SRT8 (2012-2014), Jeep Grand Cherokee SRT8/SRT, and Dodge Durango SRT. It does not fit 5.7L or 6.2L Hellcat engines.
Does the Chrysler 300 fit all years?
No. The Chrysler 300 only received the 6.4L 392 HEMI in the SRT8 trim from 2012 through 2014. Pre-2012 300 models used the 6.1L HEMI and are not compatible.
Will the PCV cap affect crankcase ventilation?
The 300028 is a cosmetic cap cover and does not obstruct the PCV valve or crankcase ventilation path. It functions as a decorative cover over the OEM cap.
What finishes are available for the 300028?
Multiple finish and color options are available including satin raw aluminum, anodized colors, and a designer cut variant with machine-cut chamfered edges. Select your preferred option from the product page variants.
Can I install the 300028 myself?
Yes. Installation requires no tools, no drilling, and no modifications. The cap threads on by hand in under 2 minutes.
Is this product made in the United States?
Yes. The 300028 is CNC machined from certified domestic 6061-T6 aluminum by Billet Technology.
Does the finish hold up under engine heat and oil exposure?
6061-T6 aluminum with anodized or satin finish is rated for underhood temperatures and resists oil vapor contamination without degrading.
Installation Instructions
- Allow the engine to cool before starting the installation.
- Locate the PCV port on the valve cover of the 6.4L 392 HEMI engine.
- Ensure the Official Billet Technology PCV Cover is already installed before fitting the 300028 cap.
- Thread the Billet Technology 300028 clockwise onto the PCV port until snug.
- Do not over-tighten.
- Start the engine and verify no vacuum leaks around the new cap.
