Thread dimensions/size note

Australian BSP thread size names can be confusing. The mm and inch naming system are only nominal conventions, they are not the physical measurements of the thread size. E.g. a common 15mm (1/2") fitting will have an actual external male thread diameter or an internal female thread diameter measurement of 20.995mm (0.825"); 20mm (3/4") fitting likewise will measure 26.441mm (1.041") 

Please refer to our BSP sizing chart provided in the last image in our gallery. Feel free to asks us any questions.

It was ok.
Size: (Pack of 1)
The product installed fine and the price was good. However, it took too long to arrive. I don't know why it took almost three weeks to get to my house. I was about to cancel the order.

I really like these filters. This is the brand I try to use, unless they're unavailable. Fast shipping and a great product. Easy to install. Great value for the money. Not driving it is the only thing that helps the gas mileage. Shipped by Amazon. Box damaged during shipping. The air filter was placed in the bottom of the box and 5 lbs of honey, 1 case (12 cans) of sardines and another item were placed on top of the air filter inside the box. The 5 lbs of honey is in a plastic 1/2 gallon bottle with bubble wrap tapped around the lid/cap. All items ship from Amazon. There was NO padding or filler in the box. Fortunately, none of the 4 items were not damaged or covered in honey. This has become a very serious issue with Amazon orders. This isn't the 1st time I've received my order and the box was as about to come apart. If I have to return something to Amazon, it's about a 75 mile round trip to the nearest UPS store. THIS IS UNACCEPTABLE!

Great quality. Worth a few bucks more
Size: (Pack of 1)
My 2004 Ram baby deserves the best especially when it’s like 5 bucks more for a good quality air filter that’s gonna be on the truck for 30/40 k miles. Don’t replace every 15K, that’s quick lube sales talk.. only if you live in a dust bowl.
