Made in the USA, this cleaner is a must-have for maintaining peak vehicle efficiency and driving enjoyment.

## Description

K&N Fuel System Cleaner is specifically designed to help increase power and acceleration, by removing performance robbing carbon buildup, resulting in restored throttle body response. Fuel cleaner is safe on all directed injected or traditional fuel injected engines.

Review: I recently used the K&N Performance+ Fuel System Cleaner (99-2050) in my 2012 Holden VE Calais V8, which has a 6.0L V8 engine, using high-quality BP 98-octane fuel. I followed the instructions, adding the cleaner to a nearly empty tank before filling it up and driving on the highway. While driving, I noticed a brief period of engine shuddering, and the check engine light came on temporarily. After a short while, the issue resolved itself, the light turned off, and the engine returned to normal. I scanned the vehicle with a high-quality OBD-II scanner, and no error codes were found. I believe this might have been a temporary effect of the cleaner dislodging carbon deposits in the fuel system, as described in the product details. The vehicle now runs smoothly, and I appreciate the cleaner’s ability to restore performance, as advertised. However, the temporary shuddering and check engine light were concerning, and I’d suggest adding a note to the product instructions to warn users about potential temporary effects during the cleaning process. This could help others avoid worry. Overall, it’s a solid product, and I plan to use it again, but clearer guidance on such effects would improve the experience. Thank you for a quality product, and I hope this feedback helps improve customer communication!

## Questions & Answers

**Q: Cada que tiempo se debe repetir este proceso?**
A: Cada 20,000 km

**Q: Is it specific for gas or diesel engine**
A: These filters are good for most vehicles engines and they do a great job filtering all the air going into your vehicle engine. I just love these and have been using for all our vehicles. Check their website for your exact match. They even make filters for your HVAC systems to save more money, as you clean vs. replacing these filters. 
I have used K & N filters for many years now, and never looked back.

**Q: So how does it clean dit engines? The cleaner goes in the gas tank and gas doesnt touch the top of the valves**
A: the fuel gets sucked in and out through the valves and therefore with the additive in the fuel, it does in fact make contact with the valves, both directly and indirectly.

**Q: are the fuel system cleaner and octane booster safe for hybrid models?**
A: Yes
