Review: Effective Cleaner with Temporary Engine Shudder - 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!
Review: Trusted brand, works as expected - It’s K&N, so I trust the brand. I’ve been using this every 6 months on my 2nd gen Tacoma with no issues. Easy to use and helps keep things running smooth. Good maintenance product.

## 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

It’s K&N, so I trust the brand. I’ve been using this every 6 months on my 2nd gen Tacoma with no issues. Easy to use and helps keep things running smooth. Good maintenance product.

### ⭐⭐⭐⭐⭐ Great additive, would recommend!
*by A***E on 22 October 2023*

If you’re wanting the quick review: Great Additive, Does work, Makes a difference, It’s only 7 dollars, Perhaps it’ll even make you go vroom vroom faster. If you’re wanting the long review: I would take a star off due to the incorrect delivery date being given, but it was through Amazon so it doesn’t really matter as it’s a big company, but overall, the additive is great. I waited until I was approximately 1-2 gallons in my tank, close to E. I put it into my tank with another additive and I feel as if I cannot mention it as it will seem like advertisement. So I put the whole bottle in before I filled my tank up to about a quarter with 93 from shell since they add detergents to their fuels(Exxon does the same) to try and clean up the fuel system better (In my theory. I’m not an expert nor advising you what to do, I’m just explaining how I used it!) from word, it’s better when you are taking a decent trip 20-30 mins/ miles on a highway with less frequent stopping. Immediately after adding the K&N and letting it kick in I could notice a difference. My ride was smooth and had more responsiveness to it as advertised on the bottle. It was a fun drive to say the least as I have a stock challenger(sxt, (R/T and SRT’s don’t hate on me it’s paid off, I’m young, cheap on the insurance as it’s in my name )). In conclusion, if you’re noticing sluggishness and decreased performance on your car, no matter the make, model, it is a great start to spend 3-10 dollars instead of going to the dealership and forking over much more than you’d like and even then, if it didn’t fix the problem, you’ll have a cleaner system after they fix the issue so at least it isn’t a total loss.
