K&N 99-5003EU Car and MotorcycleMaintenaince Kit + Cleaner + Oil

Great item. It's the genuine K&N kit but a parallel import so the box is in German I think. However, the items contained are original and work as intended. The cleaner required no effort, simply spray on, leave to soak and then rinse through. It's frightening how much muck is removed from your filter. But good to know it all stays in there rather than getting through to the engine. Although the box is in a foreign language the instructions within are available in English. They were easy to follow and the whole process, excluding drying time, took little more than 20 minutes. The only issue I have is that there is a lot of oil compared to the amount of cleaner. However, for the price and the fact that you won't be cleaning the filter that often, it's worth it.

I had purchased a second hand K&N filter for my motorbike, and thought I would try out the kit.Whilst the degreaser is just strong engine degreaser, and it works, you could use other types instead of the branded product.What I did like about it was the spray oil. It regenerates the cotton on the filter, but it also comes out in red, so you don't miss bits when re-oiling it.I still have plenty left after my service, so I'd recommend buying it if its below £12.

This stuff works really well if you do it right.I pumped the cleaner all over the filter. Then left it 10 mins or so. Then cold water wash under the tap, inside and out. Left it to dry for a few hours in a warm washroom. Then sprayed the oil on the filter.The difference is very noticeable. My car’s performance has picked up and it’s a lot smoother. I hadn’t noticed the drop over the last 12 months, but this restored it back to peak performance for me.Great product and well worth a go.

I used the entire bottle of cleaner on my filters and they cleaned up beautifully. About half the bottle of oil was needed to return them to serviceable filters. Important thing is to Read and Follow the instructions and you'll be pleased with the results.

Didn't realise how much puff I was losing due to the filter filling up with all the airborne crud, this sorted it out, made a mental note to me to clean and re-oil on a more regular basis and inspect the filter whenever I open the bonnet to top up the washers! Excellent

Product is not in English, why list item for sale in English when the product isn't!! There are serious safety warnings on the product which are not in English, this should be banned!!The product itself is a real pain to usr, hardly consider the filter cleanable when you have to use chemicals which are dangerous to the environment and burn your hards when using it!

Bought it for my K&N air filter. But my only problem which this Cleaning kit was it has no English text on the box or in the how to use instructions and even the product it self. Which made me search it up on YouTube how to use it and which one is cleaner and one the oiler.

However, this is a ridiculous price to pay for all it is, and I won't be buying again. There are many sites selling good, compatible - although not guaranteed to be so by K&N so will be going there in the future.Bought it to try, but won't buy again
