STP Pro-Series Car Intake Valve Cleaner?
 

Hey all….has anyone actually used this product, and if so, what were the results?
Is this a good idea to use? Any help or advice would be appreciated
My TL now has 130,000 miles on it, and wanted to get the carbon build up cleaned as best as possible.

Thanks for all the help!

The J37 engine uses a Port Multi-Point Fuel Injection PGM-FI, which means that when the injector is injected, gasoline is sprayed onto the intake valves, therefore the valves are always clean and do not need to be cleaned.

Carbon buildup is not a concern for our engines since they are port injected. You should always use a good fuel cleaner every oil change (put cleaner in gas tank). I use redline SI-1 and it works very well at keeping fuel injectors clean and fuel system clean.

From personal experience, I used Prestone AS730 Fuel Injector Cleaner 6 times and the only thing that helped me was removal and ultrasonic cleaning on the stand.

Using top teir gas goes a long way.

You don't need to clean intake valve carbon, as noted by the other posters.

If your car doesn't have issues at 130K...why change what you've been doing?

very cool….thank you for the info and education! I really appreciate it.

thank you for the reply, and the recommendation of Redline.
I will go that route at my next oil change.
