Replace the old or dirty air filter on your WCFAB Intake System with a Wehrli Custom Fab WCF100717 4" Inlet Dry Air Filter from GAP. This replacement air filter is designed for WCFab 4" Intake kits and S300 Single Install Kits. It offers exceptional filtration and keeps your engine protected from harmful debris. WCFab recommends inspecting the air filter every 5,000 miles, but the maintenance schedule can depend on driving conditions. To do this, simply remove the filter cover and examine the pleats. Replace the dry filter every 15-30,000 miles or when the pleats start to collapse.
Note:
The WCFab air filter is a dry media filter and is not washable. To clean it, use compressed air to blow off the outside of the filter. Keep the nozzle at least 6 inches away from the media and keep it moving. This can be done while the filter is still in the vehicle. If you want to clean it further, remove the filter and take it away from the vehicle and any engine openings. Use compressed air from the inside out, but avoid concentrating the air in one location.

A New Favorite
Format: Hardcover
This was one of my favorite new MG horror books of the year. The story was beautifully told with a strong emotional arc and eerie touches, as well as excellent ND representation. Can't recommend it enough!

Excellent (slightly) spooky read
Format: Hardcover
Another great read by Meg Eden Kuyatt. I am not much of a scary books fan, but this one was so good. I especially loved that the main character has autism and we learn so much through how different members of her family treat her.

Fun educational book
Format: Hardcover, Format: Hardcover
This book is a big hit! My 5 year old son and I read it so many times since we ordered this in April. It has cute illustration and 60 flaps and pop-ups which make the book even more exciting. And because of this, I don’t recommend this book to young kids under 3 though. Some flaps might be tricky for younger kids. Even I as a parent learned so much about construction.

Great book, but the other book of the same author is much better
Format: Hardcover
This is a very high quality book, chock a block full of information about construction sites, with lots of imaginative flaps, things that swivel, move, and fold. HOWEVER...it is not as good as "The Ultimate Book of Vehicles" by the same author. The "Vehicles" book is more appropriate for kids 3 years and up: It is still full of awesome flaps, swivels, and things that move, but it is simpler, with pictures of the vehicle, the name of the vehicle, and maybe a few names of the parts of the vehicle. You open up a flap to see inside, make it move, etc. My son found it very interesting.
The "Construction" is really aimed for older kids, I'm guessing 5 and up, maybe even older. There are just so many words on the page, and so much information. The flaps are not as interesting as the previous book, and I found many of the moving parts to be "sticky", and my 3 year old ripped quite a few out within a week of reading the book. We have not ripped anything from the "Vehicle" book.
So I would say if you have an older kid who wants to gain a lot of knowledge about construction sites, this book is for you. But if you have a younger child (3 and up, any younger and they'd destroy the book), get the "Vehicle" book.
