Electronic Fuel service needed at 25k miles?

I’m at the dealership getting an oil change. My 2021 trd Pro has 25,557 miles.

The dealer showed me a picture of a dirty cabin filter and suggested we replace it ($66). I agreed to that even though 25,557 seems early for needing to replace it but maybe I’m wrong.

Then they suggested performing a “electronic fuel injection service and decarbon intake, upper engine”. For $239. They claimed this was suggested based on mileage. I didn’t have time to research if this is really needed so I declined it.

Would like to get opinions on cabin air filter and the electronic fuel injection service at 25,557 miles.

 

Decarb is such a pile of horse shit, selling technique for those worthless stealerships. Throw some Chevron Techron in the fuel tank every few months and you golden.

 

$66 for a cabin air filter!? Save yourself the money and look it up on YouTube. You'll be shocked at how fast and easy it is to replace. That was the first thing I did on my truck. Literally takes 5 minutes.

 

Also, to decarbon the intake should be fairly simple. Remove the intake assembly than you can remove the throttle body and spray it down with some TB cleaner. Be gentle with the butterfly valve.

 

I was surprised at how dirty the cabin filter was when I changed it at 30K; much dirtier than the engine air filter.

But as was said above, this is an easy 5 min job (next time!).

 

The proper method for cleaning the carbon out of the air induction system is not just spraying cleaner straight into the intake and it's not horse shit if done properly. It's only horse shit if you've never seen the deposits that ethanol fuel leaves on valves. Scope an engine before and after and you'll see a visible difference. It's a three step process.

1. Pull the intake off and clean the throttle body on both sides of the throttle plate with some throttle cleaner and a few of these https://www.motion.com/products/sku...3LZbFPuby7ALtXubEWSTFKGZw2TQ-5GYEqYA-idoyHeig
2. Disconnect one of the vacuum connections from the intake and hook one of these up https://run-rite.com/pro/products/e...-equipment/professional-intake-cleaning-tool/ Slowly drip Seafoam or something similar into the engine while it's running at about 2-3 drops per second.
3. Add your favorite fuel injector cleaner to the fuel and then go run the engine hard to suck all the cleaner out that may have pooled in any valleys in the intake manifold.

Regular cleanings will help cut down on the heavy deposits from ethanol fuel additives. Whether or not the dealer does it at all, and whether the tech knows how to do it properly is another story all together.

Cabin air filter intervals all depend on your environment. Change it yourself, it's cheap and easy, plus it's filtering the air you breathe so you want it to be clean. Mine was sparingly dirty at 15k miles.
