Works exactly as intended!

[This review was collected as part of a promotion.] This stuff works exactly as it's intended to! I sprayed it into my intake valves and noticed an immediate difference. I didn't know that much carbon had built up! I'm glad I was sent this, because it really helped! The long-reach straw on it made it super easy to spray by myself.

Does the work and keeps it running smooth

[This review was collected as part of a promotion.] Just used the GUNK GDI Intake Valve Cleaner on my Toyota Corolla and I'm really amazed! My car had been idling rough (2006) and feeling a little sluggish, so I figured why not try this. The instructions were straightforward, and that straw made it super easy to get where it needed to go. I used the whole can in one go, and the difference was noticeable pretty quickly. Smoother idle, better pickup, and the engine just feels cleaner and peppier now. If you've got a GDI engine that's acting up, this stuff is worth a shot. No hassle, and it really delivered for me! de Hiahiv recommend! Ask Anything

A must have to keep car running efficiently especi

[This review was collected as part of a promotion.] The long straw made it super easy to do everything by myself without the need of any help. Instruction are really simple and super easy to follow. Yes the car felt like It was gonna die during the process but it didn't as long as you keep the car at 2000 rpms and do small 1sec burst. Important note is to get the car to operating temperature before starting the treatment and only apply to vehicle while it's on and at the proper rpms. The car feels smother after the treatment and the acceleration felt quicker
