If you’ve owned an older 7.3L, 6.0L, or 6.4L Powerstroke for any length of time, you already know what years of engine heat do to factory plastic. The oil fill riser is no different. They get brittle, crack, loosen up, and generally stop looking like something we want to trust for another 20 years.

So we built a better one.

Our Riffraff Diesel Billet Oil Fill Riser (RDP-OFR) replaces the factory plastic tube with a CNC-machined 6061-T6 billet aluminum riser, fitting all 1994-2010 Ford Powerstroke diesel engines.

First thing's first: pick the height that works for your truck

We offer three lengths:

• Short: 4.5"
• Standard: 5.5"
• Tall: 6.5"

That gives you some flexibility if your engine bay is no longer stock. Aftermarket intake parts, CCV setups, piping, or other modifications can make the factory oil fill location harder to reach than it needs to be.

Why we made it

The factory piece is plastic. These trucks are getting old, and we’d rather replace aging plastic with something that is substantial and built to last. And of course, we all want more billet under the hood. If you've spent a ton of time making your underhood look good, the factory fill neck just looks out of place. 

• CNC-machined 6061-T6 aluminum
• Better resistance to heat and age
• A stronger mounting point for the oil fill cap
• Three height options
• A reusable Viton O-ring seal
• Multiple anodized finishes
• Made in USA

It is a simple part, looks amazing, and takes one more brittle factory piece out of the equation.

Install: about as easy as it gets

Remove the factory oil fill riser, clean the sealing surface, lightly lubricate the supplied Viton O-ring, install the billet riser, reinstall the oil fill cap, then check it after the first heat cycle.

Finish it off

Pair it with our matching Riffraff Diesel Billet Oil Fill Cap 94-10 if you want to replace the factory plastic cap at the same time.

Bottom line: If you’re looking for a Powerstroke billet oil fill riser, 7.3 Powerstroke oil fill tube, 6.0 Powerstroke oil fill riser, or 6.4 Powerstroke oil fill tube replacement, the RDP-OFR gives you a stronger USA-made billet replacement with three height options to fit the way your truck is actually set up.
