Dinan High Flow Drop-in Replacement Filters are a direct upgrade to your factory intake system and will instantly provide better flow to assist your engine in achieving maximum performance and efficiency!
While factory paper filters function admirably, they can be restrictive to performance goals given the material used. They also require being replaced numerous times during the lifespan of the vehicle, which can add up to a substantial amount in maintenance costs. Limited performance and increased maintenance costs are never ideal but can be resolved effectively and economically in the case of filters. Dinan High Flow Drop-in Replacement Filters are constructed of 4 layers of cotton gauze that allow better flow and less pressure drop than the stock media. This equates to the engine not needing to work as hard to make the same, or more power. Additionally, the use of oiled cotton media means that the Dinan filters are washable/re-usable while still retaining excellent filtration and ensuring your engine runs clean for the duration.
When upgrading to a complete Dinan intake system for best performance, is not available, possible, or within the budget, Dinan High Flow Drop-in Replacement Filters have you covered!

Jake the Chocolate Lab Can't Tell You- But He Liked Them.
Size: 1 Count (Pack of 6)
I suppose that I should give you the details of my experience with the product. They came in a quality, resealing bag. I actually ordered this item from the Amazon page.
I got them for my parents' dog Jake- a three year old chocolate lab. I hid one in my hoodie pocket and he began zeroing in on that area after a few seconds, wondering what was in my pocket. It may just be me, but if you aren't familiar with pig ears- they don't stink or anything like that. Yes, they are actual pig ears. But they contain pork and are a decent snack for dogs every now and then. In retail we would always sell out of pig ears.
I took the pig ear out of my pocket. Jake took it in his mouth and proceeded over to his bed area where he licked the pig ear for about a minute, probably because it is salty. I don't wish to find out. He then carefully munched down on it and took a short drink of water. He then proceeded to run over and tackle me (as he is wont to do). Oddly, his breath did not stink.
I bought these as an alternative to rawhide. Two decades ago I got my parents to stop buying rawhide (about as gross as beef 'pizzle' and instead buy pig ears and deer antler chews. He seems to like them, and if they aren't causing an issue I don't see why Jake can't have one every now and then, especially when he behaves.

PRICE DOUBLED IN 2 WEEKS
Size: 18 Count (Pack of 1), Size: 18 Count (Pack of 1)
I rescue standard poodles mostly. I also train service dogs. My pack of "poodles" has all sizes and ages. This is not for profit , it is to save lives. Until 2 weeks ago -date now is: 08/17/2022- the price of these were around 20.00. My dogs all loved them. I have a buffet table with lots of storage I use to store the treats and it has room on top for all the treat jars. In the afternoon or evening, they'd get a hard, chewy treat like ears. Standard poodles love to chew . They could finish off one of the ears in minutes. These treats are quiet large and thin. They do smell but they are natural foods. NO WAY can I afford over 40.00 for 18 ears. Did pigs go exttict? Did they quit growing ears? How could They raise the price to cost double the amount? I looked at other ears on Amazon & the other brand i get which starts with a p- has not gone up. Paws- clipping. They have some Bizarre names so guess I'll just double my order for them. I have way too many dogs to give treats to. I want to be fair to all of them. They are my kids & will get the best I can offer. I did wait a few weeks before writting this. I also dropped my Sub & Save with this.
