After years of testing in conjunction with Boundary Pumps we finally have a solution for broken oil pump gears, and they're available only from KS Tuned!

The problem: Factory oil pump gears have been known to break in extreme conditions such as excessive rev limiting, extended high-RPM use and especially in the case of a loose flywheel. This breakage is caused because the OEM oil pump gears are made from sintered steel. Sintering is a cost-saving process where powdered steel is pressed into a solid form, which provides a hard, but brittle material.

The solution: The 4140 billet oil pump gear was conceived to alleviate these problems while also providing a bump in oil pressure across the RPM range. Testing shows stable oil pressure beyond 10,000 RPM! Further, the Boundary Oil Pump Gears are made from billet 4140 with a yield strength 18x stronger than OEM sintered steel!

The price includes the OIL PUMP GEARS ONLY (inner & outer gears included) and are designed exclusively for the OEM Honda Oil Pump Housing! We strongly recommend these oil pump gears be used only in a brand new OEM Honda oil pump housing.

*Fits all H-series engines and F20b, F22, F23 using the OEM Honda housing.

Bought this wallet for my husband and he loves it. It’s softness, design, ease of use, perfect size and great value for the money. The magnet strength is perfect. Bought for Christmas and he’s still telling me how wonderful it is. Great product .

Quality Meets Functionality
Color: Black8017, Material Type: Leather
Very impressed with the quality material and functionality of this wallet, I had to buy a second one. (Coffee + Black). It opens and folds-out like a breeze in your hand and stays closed when not in use. The pop-up card holder mechanism works well too. The overall compact size makes up for the thickness of this wallet. It is thick. I wouldn’t recommend sitting on this one, but it’s small enough to keep in a front pocket while seated.

Nice wallet but...
Color: Tiger Eye8018, Material Type: Leather, Color: Tiger Eye8018, Material Type: Leather
I've been using this Bulliant wallet for a few weeks now, and it's been a solid upgrade from my old one I carried. I like the design of the wallet. It is sleek and clean looking. It hold a good number of cards without feeling bulky. When I first loaded the wallet up, the card slot was a little tight but that is to be expected. As far as durability goes, the wallet holds up. It isn't made of cheap material. It protects my cards and keeps everything organized. The only downside I would say is if you wear your wallet in your back pocket it is going to be a little bulky. Also if you have a lot of cards like me, you will run out of room and have to decide which cards to carry. But overall a good wallet that I would purchase again.
