Another small business Climate Tax victim.
Local concrete crew on the way to an out-of-town job to pour a house pad. DEF warning comes up, they stop and add DEF. warning still on, they try to make it home, they are they are 200 miles from home. truck shuts down to 5 mph. 6-man crew, sits and waits for the owner to come with a trailer to pick them up. (tow bill would be outrageous) concrete trucks were already loaded and waiting. They have to be redirected (not for free) so......what's that cost the small business owner?
paying his 6-man crew to stand around all day
redirecting the concrete
losing his whole day to come get the truck and crew
explaining to the next contractor why the job is off schedule now
trying to get back on the concrete schedule
1000$ repair bill
why???? because the DEF injector wasn't sure if it was spraying DEF into to exhaust.

WE HAVE TO FIX THIS! ITS KILLING SMALL BUSINESSES!

We here at Sims Diesel have been receiving numerous calls in the past few weeks about a certain service being performed.

Let me clarify some things for you.

Just because you....
saw it on YouTube
saw it on TikTok
heard from your cousin's, next door neighbor's, uncle that used to change his own spark plugs.

IT IS STILL ILLEGAL TO DELETE YOUR DIESEL TRUCK
Don't order that Chinese crap you see online. The EPA is watching those sites.
If anybody would know about this subject, don't you think it would be us?

PIC FOR ATTENTION ONLY

First off let's get this disclaimer out there
THIS IS EPA COMPLIANT, CARB COMPLIANT, COMPLETELY LEGAL
We have had multiple customers ask us about the 6.7 Cummins intake air heater nut failure. This is when the nut loses good connection, comes loose, then gets sucked into the engine causing a catastrophic failure. Until today I have told many customers that it is such a rare occurrence, that we have never once seen it. I tell them not to worry about it. Today we saved a customer a 20,000$ engine. This marks the first time we have seen this issue. I will now be recommending this kit which eliminates the issue by redesigning the intake air heater setup, while improving air flow and efficiency at the same time. We can install this kit for @2000$ they come in red, black and natural. Give us a call to have peace of mind about your engine!
Did I mention its EPA legal???
