MUST USE!

Dan September 4, 2025

If your auto has a direct injection engine, you need to use this product every 20k miles to keep the carbon build-up at bay. I used this on my 2017 Silverado 5.3 Vortec at 140k miles and it cured the rough idle and added 2.0 MPG!!! I wish I knew about this product much sooner. Super easy to use and highly recommended!

Powerful yet easy-to-use system

Chad June 3, 2025

For my direct injection truck, STP Pro Series Intake Cleaner is a maintenance must-have. Direct injection engines notoriously build carbon on intake valves, leading to rough idle, power loss, and poor fuel economy. I use it every 10,000-mile oil change. The process is simple: * Prep: Warm engine, turn off, ensure ventilation and safety gear. * Access: Expose throttle body by loosening air intake boot. * Connect: Hang the cleaner's hose from the hood, insert past the throttle plate, and re-secure the boot. * Apply: Turn the cleaner to "on." Start engine, hold 2-3 times idle RPMs for 9 minutes while it dispenses. * Post-Clean: Turn off, remove hose, reattach boot. Drive for 10-15 minutes to clear residue. I consistently notice smoother idle and better acceleration after each treatment. It proactively prevents more costly carbon cleaning. For ease of use and tangible benefits, STP Pro Series is a reliable choice for direct injection engine care.

Must get for GDI engines

Kenneth April 27, 2025

If you have a GDI engine with some miles I highly recommend this product. This product made a good improvement in my Ecoboost Explorer.

Worked for me

Unknown March 16, 2022

Took care of idling hiccups when stopped at traffic lights. Hooked it up to air hose pre-turbo but POST-MAF sensor. Car runs great now.
