K&N 57i Series induction kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. The extra surface area of these open-air air filters provides even more airflow at lower restriction than a K&N O/E replacement filter which is limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adapters are made from high quality materials such as steel, aluminum, silicon or reinforced nylon to ensure long life. 57i Series Intakes are not legal for use in California and other US States adopting California emission standards.- Guaranteed to increase horsepower

Our puppy loves this mat
Color: Latte coffee, Size: 35"L x 27"W x 1.5"Th, Color: Latte coffee, Size: 35"L x 27"W x 1.5"Th
Our new puppy loves this bed for his crate. It is thicker than many of the other crate mats we have looked at and extremely soft. I also appreciate the little silicone pattern on the bottom that keeps it from moving around since we take it in the car. I can’t speak to the self warming piece though. We have a self warming bed for our cat and it has reflective fabric on it similar to what you find in a Columbia omniheat coat. This has nothing like that. Either way it is our puppies favorite mat and so far one of the few he hasn’t chewed to bits. That alone makes it 5 stars for me.

Cat Approved
So I have several self warming pads, this is the first one all three cats like. The outer cover is similar to the fake rabbit fur blankets and that was a huge hit in my house, everyone kneaded it excessively. While the pad isn't thick it does generate some heat keeping my smallest cat warm. And even my fattest guy liked it. It is made well and I am already ordering a second.

Small cat (or dog) warming bed.
Size: 20.0"L x 16.0"W x 0.5"Th, Color: Grey
LOVE this warming cat bed!!
With a tiled or cement floor, this is an ideal strategy to remind little pets that this is a warm spot for you to lay your head <3

Great.
Size: 27.6"L x 18.8"W x 0.5"Th, Color: Grey
My cats love these. Will choose these over and over again. I had to buy multiple so they could each have one. Does seem to help keep warmth in. It’s also easy to clean.

Warm, Comfy, and No Electricity Needed
Size: 20.0"L x 16.0"W x 0.5"Th, Color: Grey
This self-warming cat mat works well — it reflects body heat and stays noticeably warm without plugs or electricity. The surface is soft and cozy, and most cats seem to take to it quickly. It's lightweight, easy to clean, and fits well in beds, carriers, or on furniture.
It’s a bit thin, so adding extra padding underneath may help. Also, it can slide on hard floors, so best used on carpet or fabric surfaces.
