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.

Best laptop sleeve on the market — and I've tried plenty!
Size: 13.3 inch, Color: Black, Size: 13.3 inch, Color: Black
As someone who reviews products regularly, I have pretty high standards and I don't hand out 5 stars easily. But this MOSISO sleeve? Completely earned it. I've tested a lot of laptop cases over the years and this one genuinely stands out from the crowd. The quality is immediately noticeable right out of the box — the material feels premium, looks sleek, and has held up flawlessly through heavy daily use. No pilling, no wear, no disappointment. The fit on my 13-inch MacBook is perfect. Snug without being tight, and sliding the laptop in and out is effortless every time. The zipper is smooth, the padding is substantial, and it slips into my bag without adding unnecessary bulk. I've gotten multiple compliments carrying it around at coffee shops and the office. I also accidentally knocked my bag off a chair recently and my MacBook came out completely fine — so the protection is definitely real and not just marketing fluff. For the price point, the value here is genuinely hard to beat. I've reviewed sleeves twice the cost that don't come close to this level of quality and finish. MOSISO really delivered with this one. If you're on the fence, trust me as someone who does this regularly — it's absolutely worth it.

PURRRFECT
Size: 16 inch, Color: Deep Teal
I purchased this item on April 12, 2026 and received it on April 16, 2026. It is just PERFECT!! The right size, the color teal is just awesome looking, the quality of the material is strong and durable, the lining inside is well padded to protect the laptop, the zipper glides easily and very strong. The pocket outside has ample room to put miscellaneous items. I love it and I love it!!!! Go for it! It is worth the money.

Good-looking case that is well made
Size: 13.3 inch, Color: Bright Rose
This case is well-made. The material is non-slip, the zippers are easy to use, the stitching is quality, and the case is a perfect fit for my 14" MacBook Pro M5 even with a Speck protection case installed. All that being said, my favorite feature is the color. WOW! It definitely will not get lost in my office or in a dark backpack or briefcase. I'm not sure how I'll use the front pocket. Off the top of my head I'll probably put a pen, slim notebook, and business card. I'll update this review if this doesn't work for me. One more thing...I also bought the 13" Chartreuse for my Citrus MacBook Neo that has a MecBevia protection case. Perfect fit!

Sleek, Durable Laptop Sleeve That Punches Above Its Price
Size: 13.3 inch, Color: Red
Right out of the box the sleeve felt premium—sleek exterior, soft interior lining, smooth zipper—and it’s held up flawlessly through daily use with no pilling or wear. My 13‑inch MacBook slides in snugly without adding bulk, and the padding gave me real confidence after I accidentally knocked the bag off a chair and the laptop came out unscathed. The front pocket fits my charger, hub, and other small accessories neatly, making it practical for coffee‑shop days, though I do wish it had a grab handle, but it is ok. For the price, this sleeve delivers excellent protection and finish that rivals much more expensive options.
