    Overheating, cavitation, and poor coolant circulation can mean excessive wear and damage to components. Use the Boyesen Supercooler Water Pump Cover and Impeller Kit and you’ll get superior cooling that keeps your bike running at its best.

    By increasing the coolant passage size, creating a high-flow impeller, and smoothing all interior surfaces to reduce friction, the Supercooler pumps out more coolant at a faster rate than your stock water pump. The Boyesen cover looks great but it keeps things simple too since it has the same footprint as your stock unit. No need for any special gaskets or fitment. Just bolt the Supercooler up like it’s stock.

    With high-revving, hard-working dirt bike and ATV engines, temperature management is key to keeping your machine running well. Make sure you have the parts to keep it that way with the Boyesen Supercooler Water Pump Cover and Impeller Kit.

    Specs:
  • High efficiency water pump and cover for increased engine cooling
  • Investment cast from aluminum alloy for lightweight strength
  • Same footprint as stock parts for bolt-on installation without special gaskets or fitment
  • High-flow impeller moves more coolant than stock parts
  • Less cavitation on impeller means better efficiency and longer impeller shaft life
  • Higher flow rate with larger diameter passages and low-friction internal surfaces

A must add on to any cooling system!
High quality finish and fit my bike perfectly with factory bolts from factory water pump. There is a big difference when you compare the 2015 KX450F water pump housing and impeller. The pump came with a gasket. I ordered an oem gasket along with the pump. The factory gasket works perfectly with the pump. The inside of the pump housing is much smother and larger. The pump housing does stick out a little further and does touch the factory plastic water pump guard. After several rides it has not damaged the factory water pump guard. The impeller is much better quality than the factory impeller.

Easy to install. Looks great on the bike. I would highly recommend this to anyone who owns a dirt bike.

Keep your temps down...
Arrived promptly from RMATVMC and immediatly went onto my bike. Instructions were clear and informative for a painless install. Have approximately 10 hours on the supercooler and the temps have been noticeably cooler!

Quality, but installation problems.
Great product that keeps the bike cooler and looks good.
OEM water pump bolts do not fit on KX450F, the shoulder is to large for holes. You'll need new ones. You'll also need to trim down the plastic OEM deflector installed on the right side, it rubs on the pump if not.

Quality product
Nice upgrade. OEM inlet was substandard. (milled poorly)
Boyesen pump is lager with metal impeller, capable of high volume flow. The price is a little hight and a new gasket would be nice. But.. you get what you pay for . Very nice product.

Expensive but totally worth it. KTM no longer boils, fan doesn't come on
I received one of these cheap and second hand, threw it on my KTM expecting nothing. Wow was I surprised night and day difference on motor temps and cooling. Nothing short of amazing. The bad part is I have two more KTMs and a Husky I will now be buying these Boyesen water pumps for, grrrrr...

What is your opinion on this pump vs. radiator fan?..Both would be overkill I believe.
Michael A on Apr 22, 2017
BEST ANSWER: I have both the fan and the Boyesen pump. I installed the fan first after my KTM 350 was boiling over all the time on tight trails. (it's ridiculous that ktm ever sold this bike without a fan) The fan helped but it would still sometimes overheat so I got this water pump. It made the situation even better and now the bike never overheats but the fan will still kick on sometimes, which tells me that it's good to have the fan there. I also use engine ice in the radiator.

Is it difficult to install? Do you have to take the engine apart to put that c-clip around the impeller?
Lanc B on Jan 1, 2017
BEST ANSWER: If you own a Kawi, its easy... the impeller unbolts... just be careful holding the impeller, it's sharp... I think the hondas have a 10mm nut built into the impeller which makes it easier... no c-clip that I am aware of. Hope this helps.
Does this product come with a gasket?
Arron V on Jan 23, 2017
BEST ANSWER: This product indeed comes with a gasket. I would recommend changing to a high performance coolant as well if you havent done so already. You will have noticable gains in power and your machine will run noticabley cooler.
Does it come with gasket?
A shopper on Oct 7, 2016
BEST ANSWER: No it does not come with a gasket. Highly recommend installing a new gasket at the time of installation, depending on the age and milage of your machine.
Does this come with the large o ring?
Bailey A on Jan 20, 2019
BEST ANSWER: I think you’re referring to the housing seal? If memory serves, I used the seal from my OEM pump when I replaced it with the Boyesen pump. My bike was basically new at the time.
I honestly don’t remember for certain, as I installed this almost 2yrs ago.
Does this come with the the large o ring?
Bailey A on Jan 21, 2019
BEST ANSWER: The bike I put this on is 2007 crf450r and it came with everything I do not remember exactly because it’s been over 2 years ago but I do remember how well it works and it greatly improved the performance but the crfr also has a oversized radiator/oil cooler all installed at the same time

BEST ANSWER: If the question's will the "Splitstream Hi-Flow Water Pump Upgrade" be compatible with the other Boyesen and/or Pro Circuit water pump kits, the answer is possibly. Splitstream hasn't stated that they're compatible or not, it would have to be tested. I personally don't foresee any conflicts.
