Most air filters on the market are a compromise. Many high-performance filters deliver better airflow, but sacrifice filtering ability and engine protection in the process. OEM filters, which are usually made of paper, filter adequately but at the expense of airflow. And airflow decreases as these air filters become dirty. Not so the K&N air filter. K&N air filters increase airflow without decreasing filtration ability, and the increased airflow remains consistent throughout the filter's service interval. The secret is in the K&N filter's construction.

K&N's initial goal was to develop a filter that would deliver increased airflow during dirty, dusty off-road racing conditions. Increased airflow improves the efficiency of the combustion process, increasing horsepower and torque. But just increasing airflow without ensuring adequate filtration under those conditions would result in a ruined engine. K&N's solution was a filter design consisting of 4 to 6 layers of cotton gauze sandwiched between two aluminum wire screens. The cotton is then treated with a specially formulated grade of oil that causes tackiness throughout the cotton’s microscopic strands. The resulting K&N filter not only delivers increased airflow while trapping dirt particles that could harm your engine, that level of airflow is maintained even as the filter gets dirty. The layers of oiled cotton fibers in the K&N filter trap dirt particles that are smaller than the holes in the filter media. The thickness of the layers also allows the K&N filter to trap dirt and dust on many levels, trapping more dirt without decreasing airflow. Contrast this with a paper filter that only traps dirt on its surface; as the surface area becomes clogged, the airflow rate goes down.

Each K&N air filter is custom designed to fit into your existing factory air box. The K&N filter is economical because it's the last air filter you'll have to buy for your car. It can be washed and reused many times, and since you can usually drive up to 50,000 miles between servicing, you won't have to clean it very often. And every K&N filter is backed by K&N's Million Mile Limited Warranty. By the way, check the CARiD reviews and read what the customers think of K&N porducts.

Scent: Bourbon & Oak, Size: 16 Fl Oz (Pack of 1)
The scent is incredible — warm, slightly sweet bourbon with a rich oak finish. It smells high-end without being overpowering. It lingers just enough to notice but doesn’t clash with cologne. Performance-wise, it delivers. It cleans thoroughly without stripping and leaves hair soft and manageable instead of dry or heavy. For a 2-in-1, it actually conditions well — which isn’t always the case with combo products. I originally bought it as part of a gift set for my father, and he’s since had me repurchase it four times — so that says everything. If you like warm, masculine, slightly woody scents and want something that performs as good as it smells, this one truly hits the ball on the head. Definitely a repeat buy.

Husbands Favorite!
Scent: Bourbon & Oak, Size: 16 Fl Oz (Pack of 1)
This brand is my husband's favorite! He uses the shampoo/conditioner and the body wash. He says it lathers and suds up pretty well. The smell is great and lasts a good while. The only thing is he wishes it came in a bigger bottle.

Next Level "Hotel" smells
Scent: Bourbon & Oak, Size: 16 Fl Oz (Pack of 1)
I have been searching for a shampoo that not only leaves my hair feeling clean, but also smells great. Cremo has frequently checked a lot of boxes, and this shampoo is no exception.I adore the bourbon and oak scent. Despite giving some hotel shampoo vibes, it smells great once in the air, and I feel good showering with it. It leaves my hair feeling clean and no oily, but still soft. I have thicker hair, but this works in easily. Bottle came perfect, no leaks! Only complaint is I would like a larger bottle with a pump to user easier in the shower!
