K&N 99-0621 Power Kleen; Filter Cleaner - 32 oz Trigger Sprayer Product Reviews

Monday, July 9, 2018 - Part 99-0621
The K&N products are fantastic I have been using them on all my cars for years However, the Power Kleen bottle was opened and had split all over the inside of the box when i received it. And, everything inside the box was covered with liquid product, plus I ended up receiving only half of the product itself Nevertheless, still happy with K&N products.

Only 3 because my bottle of filter cleaner blew up in the box. Not worth the hassle of returning it. As products go, can't go wrong and totally worth it. Been using K&N filters on a whole Lotta motors for, 40yrs. Filters are the best and don't fail.

I order this item along with two others. One item arrived quickly and when I called the company to inquire they offered to send this and another item out immediately. I was then contacted by UPS to tell me that they could not deliver it because the packaged was damaged. Another packaged was sent and UPS delivered it and I got filter cleaner all over me and the front entrance to my house. I again contacted Power Kleen and they offered to refund my total purchase price and send another package. Finally a package arrived that was not damaged nor was it leaking product all over the place. I think the whole ordeal took close to six weeks from the time I first placed my order until the undamaged packet arrived. The product itself is great, customer service finally delivered what they promissed, so......

This was a small order. I had a leakage problem upon arrival and called about it. I stated what happened and was told I would get a replacement that day. A few days later a new package with no damages arrived on my doorstep. Great 5 star service to K&N. Thanks, Mike

Works great, I like it better than the smaller bottle. The pump on the smaller bottle died shortly after I bought the product. I have 170000 miles on my truck and I have used the K&N filters and clean system almost since the truck was new.

Does a fantastic quick job cleaning my K&N lifetime air filter. Buying the filter was one of the best purchases I've made. The cleaner appears to get everything clean after one dosing.

Always happy with K&N filters and filter cleaning/oiling products. Price is fair and shipping is fast. Previously purchased at store, but will be ordering in the future instead. Use them on our 2009 and 2010 Pontiac Vibes (2.4L). Vibe is a Toyota Matrix. All parts are interchangeable, except for the body and certain interior trim pieces. With your help, these two should see many miles. Thanks.

This is a great product I bought it to clean my bikes K&N air filter however I have found it works great to clean everything that is oily from the bikes undercarriage to the garage floor.I previously used break cleaner to clean the oil drain pan after use. No more. This spray does such a great job I wouldn’t use anything else.
