Happy to have found them. Subaru wants to sell you the entire housing. This is the only place I’ve found that sells the screens. Thanks!

So glad I found them! Kia wanted $1038 for a new oil pump balancer. They do not sell nor have part numbers for the internal bearings which were the problem. AEP had the bearings in stock, and a great web page to make sure I was ordering the correct model. Problem solved for under $60.

My customer tore apart his Kia balance shaft assembly in an attempt to diagnose, and I was able to source the needed bearing kit from AEP, have it shipped in several days, and get the vehicle back on the road for close to a thousand dollars less than if they were to buy the entire balance shaft assembly. They have parts I was not able to find elsewhere, whether from dealers or online!

Response from the owner 16:24 21 May 25

Hey Sara - thank you for the detailed review! We are happy to hear you saved a ton of money on your KIA 2.4L rebuild!

Camshaft was a perfect match for my broke OEM part. Looks to be much better made and stronger than the original.

I ordered 2 OCV for my 2018 WRX from the Subaru dealer and I forgot to order new gaskets/o-rings though. I searched and with shipping, the dealer wanted almost $30. I felt that was ridiculous so I continued searching. I came across AEP and they had the gaskets, including shipping for just over $15 which is half the price as the dealer!!!
The dealer who sent me the 2 OCV messed up and only sent me 1, I received my order complete from AEP before even receiving my other OCV from the dealer and I live on the other side of the country!
Everything was packaged well and as far as I can tell, they are genuine Subaru parts. AEP even sent me a pen in my order, the pen seems to be of good quailty as well, not just some cheap one you would get at the bank lol.
Any future purchases for any of my vehicles, AEP will be the first place I look!!!
Very Impressed, Excellent job AEP!!! Thank you!!!

Today I received my order from AEP a and I am very pleased doing business with this company! I was searching for a specific part and to my knowledge AEP is the only reputable company online with with this part. I received my order on time in a timely manner. And when I opened it AEP also included a rubber gasket as a courtesy!! I truly appreciate this company and I am very happy doing business with this company. I 100% recommend to anyone looking for quality parts for their vehicle!

Great company to deal with. Had a small issue with a set of camshafts I ordered for my Jeep. Emailed them Memorial Day and Kyle got back to me with in minutes. Explained to him some how I was sent two of the same side camshaft. The following day I had my replacement camshaft on the way next day air. Thanks again for all your help Kyle.
Edit* Ended up banging up my passenger side cam and ended emailing Kyle to see if they had one ready to go. He got right back to me and added expedited shipping at no extra charge for me. Awesome customer service! So far the camshafts I ordered have performed flawlessly and at a fraction of the cost of the Mopar. Thanks Kyle.

Ordered from AEPs online store because they offered better quality components for my vehicle at a better price than any other local or online seller. I was pleased with the ease of transaction from their store and speed of delivery. All came well packaged in great condition. I would definitely order from AEP again.
