This product helps clean internal fuel system parts, while safe on catalytic converters and oxygen sensors. Review: Works! - First of all, I have to admit that the product actually seems to work. I currently use it for 4 vehicles. Since one bottle is enough for 68 liters of gasoline, I have weighed it accordingly and calculated on the tank capacity of my vehicles. I originally bought it for my Yamaha Raptor to give it something beneficial, since here in Paraguay we have gasoline with 96+ octane maximum and I have the Big 3 installed on my Raptor. After seeing some videos on the internet where octane boosters were tested in cars on a dynamometer and a power increase of 3 to 6% was MEASURABLE, I thought: I'll try that too. A direct increase in performance I have now not necessarily felt. But the engine runs very well. Good response. Definitely not worse! Next was my Yamaha WR450F. Again, I must say, it definitely does not run worse. But since the bike has endless power anyway, I don't notice any "extreme" boost in power here either. What I have to say though: It has helped to optimize the combustion. The exhaust is much less sooty! Now my last experiment: We have 2 China scooters with 125cc and carburetor technology and the two parts run far from optimal. When cold, they hardly start at all and they smoke non-stop out of the exhaust. Despite several times disassemble carburetor and clean and adjust, nothing could be improved so far - and in the beginning, the scooters ran very well, without problems. Now the miracle! Again, I added the K&N octane booster and wow: after a warm-up and then full throttle and smooth driving for a few minutes no more smoking from the exhaust, no backfiring, no knocking. So far I have ALWAYS had problems with knocking with my scooter. Especially at full throttle and the heat here because the engine is only air cooled... But since I put the booster in I have not had one jerk, stutter, knock or misfire. Both vehicles run SIGNIFICANTLY better. Cold starting works much better now too! So in conclusion I can say, especially with carburetor technology and air-cooled engines and that in warm climates, the octane booster pays off!

The material of filter is the same. The design only differs. ONLY thing to note is that the filter should be washable and reuseable type. The filter type should be oiled filter. If its dry filter then you can use the spray to clean it only. just do not oil it once cleaned.
