Monster‑Ram Intake Prevents RAM 6.7L Engine Failures

6.7L Cummins engine damage from grid heater bolt failure

Due to heat cycles and a 30Hz vibration at idle, a fastener in the 2007-2024 RAM 6.7L Cummins stock air intake heater (grid heater) loosens, arcs, melts, and falls into the intake manifold. Gravity forces the $1 bolt to roll downhill into cylinder #6. In many cases, this results in severe piston, valve, and head damage or total engine failure. While hundreds have caught it in time like Joe, others have replaced pistons, repaired cylinders, and heads. Some have replaced entire engines.

00:00 Oh no. Worst case scenario. There it is. The dreaded grid heater bolt is failing. Imagine owning a Ram knowing there’s a $1 bolt ready to kill your Cummins engine. Grid heater failure is real and it’s real expensive. One of our customers brought in his truck and you’ll never believe what we found. No

00:24 way. I’ll let the guys explain. This is a 2016 Ram with about 107,000 miles on it. Did it have a P2609 code? No present. [Music] Ready. Oh, where’s the bolt? The whole piece is gone. Is the bolt in there? Looking at valve six in here and we cannot find the bolt. Magnet time. Yes, sir. Go fishing.

01:00 Got it. No way. [Music] Look at that engine killer right there. It’s ridiculous. Look at this, Matt. Another one. 30 grand. 30 grand for a whole new Cumins engine. That’s your bolt. This was about to fall into cylinder 6. Oh, wow. and get ingested and be beaten up by the piston in the head. You were

01:25 hours away from losing an engine. This becomes loose right here over time, vibration and heat cycles. And as soon as it elongates or the nut backs off one or two threads, it starts to arc basically like an arc welder. And when you arc, it superheats and it melts this

01:43 nut and bolt and it drips down. Cuz this of course is upside down right now. This would be flipped like this. And that bolt drops off like a stalactite from the top of a cave right into the intake manifold and wanders down into cylinder 6 and gets eaten up. Passes through the valve

02:03 and gets eaten up by the cylinder. So, I’m lucky today. Very lucky today. Buy a lottery ticket, my friend. All right, Monster Ram time. Included with the Banks Monster Ram is the billet high flow intake plate. And as you’ll see here, there’s no grid heater. It’s free flowing. nothing to

02:18 fall into the intake manifold. We include a coil heater that threads into the top of the Monster Ram. Let’s install this here. Factory horn inlet. Monster Ram inlet. Look at this. Can’t even get two fingers in there. I mean, look at this. That’s the opening. Put the Monster M in.

02:37 For those who say this only happens to one in a million, tell that to all the guys who’ve lost engines. It’s a game of Russian roulette that I wouldn’t want to play. The 50-state emissions legal Banks Monster Ram gives you peace of mind and performance. It extends turbo life,

02:54 improves throttle response, and boosts fuel economy.

The great news is this catastrophe can be avoided by installing a Monster-Ram. The intake system completely eliminates the grid heater so there’s nothing to fail. And, for a limited time, the complete kit is more affordable than ever, thanks to Banks Monster-Ram Summer Promotion.
