Your turbo can only breathe as well as your intake allows.

The DIESELSITE 4" Inlet Washable Air Filter gives your diesel the airflow it needs with a high-capacity design built for performance applications. The 4-inch inlet makes it easy to retrofit into many open intake setups, while the reusable pre-oiled filter design means you can clean it, service it, and keep putting miles on it.

Because your diesel deserves clean air—and plenty of it.

Nobody wants to tear into a truck when the weather turns cold.

Summer is wrenching season—the perfect time to take care of the maintenance items that keep your 6.0L Power Stroke running strong. When the supply chain for 6.0L glow plugs became unreliable, whether OE or aftermarket, DIESELSITE decided to build a better solution.

DIESELSITE Glow Plugs are engineered to heat faster, reach higher temperatures, and deliver reliable performance throughout their service life. The stainless-steel body helps prevent corrosion while making future removal easier when it's time for replacement.

✔ Engineered specifically for the 2003-2007 Ford 6.0L Power Stroke
✔ Faster heat-up and higher operating temperatures
✔ Stainless-steel construction for corrosion resistance and easier extraction
✔ 100% factory tested to meet OE standards—with improvements

Don’t wait until the first cold morning to find out your glow plugs are tired. Handle the maintenance now and enjoy the miles later.

If you've ever fought an IPR valve on a 7.3L, you already know why this tool exists.

The DIESELSITE 7.3L IPR Installation Socket is designed specifically to remove and install the Injector Pressure Regulator without risking damage to the valve. With a stainless-steel construction and multiple drive options, it helps make one of the most awkward jobs on a Power Stroke a lot less painful.

Sometimes the right tool doesn't just save time—it saves parts.

Who has wrestled with an IPR before?

MORE BOOST. MORE PULL. LESS STRUGGLE.

The DieselSite Adrenaline HPOP for the 1994–2003 7.3L Power Stroke is built to wake these trucks back up when factory oil pressure just isn’t cutting it anymore. Better fueling response, stronger injection control, and the kind of mid-range power you feel the first time you lean into it under load.

Dirk Z. put it plain and simple after the upgrade—his truck went from barely handling a 4,000 lb tow to pulling with confidence again, calling it a game-changer and saying he’s now a lifetime customer.

That’s what happens when oil pressure finally matches what your injectors are asking for.

Built for work. Built to pull. Built to last.

SAVE THE TRANSMISSION. SKIP THE FULL REBUILD.

If you’re running a ZF5 or ZF6 behind a 6.9L or 7.3L Ford diesel and dealing with input shaft wear, DieselSite’s Input Shaft Repair Kit is the clean fix that keeps you out of a full teardown.

Instead of pulling the entire transmission apart, this kit targets the real problem area with a precision-fit hardened sleeve that restores the worn input shaft surface. You also get a new pilot bearing, installation driver, and alignment bushing to make the job straightforward and accurate.

It’s built for trucks that work—daily drivers, tow rigs, and old-school diesels that still earn their keep. Tight engagement, better longevity, and a smarter way to deal with a common failure point.

Simple fix. Big savings. Back on the road faster.

STOP CHASING BOOST LEAKS.

If your 1999-2003 7.3L Power Stroke is still running factory manifold boots, they're probably soaked with oil, losing grip, and bleeding away valuable boost pressure. DieselSite's Manifold Boot Kit replaces those tired factory connections with heavy-duty, oil-resistant boots designed to hold under heat, pressure, and years of abuse.

Built with reinforced multi-ply construction and Fluoroelastomer-lined material, these boots are made to resist the oil contamination that causes stock boots to deteriorate and leak. Whether you're towing, daily driving, or turning up the boost, this is cheap insurance against lost performance and blown boots.

✅ Eliminates common boost leaks
✅ Handles higher boost levels with confidence
✅ Oil-resistant construction for long service life
✅ Direct fit for 1999-2003 7.3L Power Stroke trucks

💥 OEM HAD A WEAK SPOT… DIESELSITE FIXED IT. 💥

The factory crossover pipe was never built for how these engines actually live. Heat cycles, expansion, vibration… all of it stacks stress right onto the bolts and gaskets until leaks start stealing boost and efficiency.

DieselSite stepped in with a real solution.

A stainless steel bellowed crossover pipe designed to flex with temperature changes instead of fighting them. That means less stress on the system, fewer blown gaskets, and a setup that holds together the way it should under real-world conditions.

They didn’t stop there. The V-band design tightens up the seal and makes installation cleaner and faster, while the pre-welded EGT b**g means your gauge setup is ready without drilling or guesswork.

More control. Better sealing. Smarter design than stock ever offered.

DieselSite didn’t just replace OEM—they improved it. 🔥

💨 “AMAZING!” – REAL-WORLD RESULTS FROM REAL BOOST. 💨

Nothing sells a Wicked Wheel like the guys who actually run it.

Robby C. dropped it in and immediately felt the difference—faster spool, stronger response, and even a bump in boost. More turbo noise, deeper tone down low, and a truck that just feels more alive the second it spools.

That’s the whole point.

Not theory. Not hype. Just a simple upgrade that sharpens how your 7.3 responds when you get into it.

Stock wheel out. Wicked Wheel in. 🔥

STILL FIGHTING A HEAVY STEERING WHEEL?

Your 7.3 Power Stroke's power steering system may be working harder than it has to.

The DieselSite Overdrive Power Steering Pulley Kit increases power steering pump speed and delivers up to 10% more fluid volume for improved steering assist. The kit even includes the correct belt for a straightforward installation. It's a simple upgrade that can make a noticeable difference when maneuvering, towing, or turning larger tires.

Less effort. Better steering response. More confidence behind the wheel.

Because wrestling your truck through every parking lot isn't part of the job. 💪

The vacuum pump quit pulling its weight years ago. 💀

The DieselSite 6.5L Vacuum Pump Elimination Belt is for the guys cleaning up the weak links on their GM 6.5 build and making the engine bay simpler, tougher, and less likely to leave them stranded. One shorter belt, less clutter, less nonsense. 🔧

If you’re already running a Turbo-Master setup, this is the next move. Delete the dead weight and let the old Detroit diesel breathe a little easier. Because nothing ruins a good tow rig faster than a seized vacuum pump smoking the belt on the side of the highway. 😈

Simple upgrade. One less failure point. More peace of mind when the truck’s working hard.
