    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

Substantial Improvement
Aluminum impeller is a substantial design improvement over the stock plastic squirrel cage type pump design. It is obvious to me that this will flow more coolant and will be more reliable than stock.

Simple install about 20 minutes. We will see how long it lasts on the brutal rockyl single-track.
This along with Evans no-boil coolant keeps this Kx450f running alot cooler on the single track that I mostly ride. The impeller is about 25% larger than stock and it really moves the coolant.

Great product and great support
Purchased this 1 year ago for my 2017 big bore 270sxf. It's done a great job. I had an issue with it at the end of the year. I email Boyesen Customer Service and they mailed me replacement parts next day. Overall this product and company has really helped me a lot. I highly recommend any product they make!

A must have part
Super easy install, directions are easy to follow and kit comes with everything you need. You dont realize how much better this is over stock until you take the old impeller off and compare.

Boyesen Supercooler Kit
This is a must have for KTM 2 and 4 strokes as the OEM impellor is plastic, has short straight blades, and the OEM cover has smaller inside bowl with "steps" in it compared to Boyesen's aluminum impellor with curved, 2x the height blades, and larger inside like a bowl with no "steps" allowing smoother, faster coolant flow. This reduced my temperature 20 degrees, 10 degrees less with SamcoSport T-hose frame hose, and another 5 degress using Tusk Silicone rad hoses, resulting in 35 degrees cooler in my 2016 350 XC-F; I also use Evans Waterless Coolant as extra protection in this bike and my 2017 Yamaha YZ 250

Top of the line aftermarket pump

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.
will it fit the yamaha yz450fx? (same part number for the 250 and 450)

I have a 2017 Yamaha YZ450FX and it is currently leaking coolant out of the weep hole. I was told my seal was bad.Does this kit come with gasket and seal,and will this resolve my leak?
Chris L on Jan 13, 2020
BEST ANSWER: It's an O-Ring in a recessed grove, I used the old one from the bad cover. (no O-Ring provided) The Boyesen Supercooler water pump help my overheating issue.(2011 Can-Am Commander)
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.
Has anyone installed this product on a 2014 can am commander 1000?
A shopper on Apr 7, 2020
BEST ANSWER: No, Installed on my 2011 Can-Am Commander 1000. Works great. stopped the overheating issue I had,so far. installed fall 2019.
Does this come with new water pump seals?
CHAD H on Jun 27, 2019
BEST ANSWER: Yes I believe it comes with everything you will need for the change over. It’s an amazing product!
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
Can anyone confirm that this fits the 2018 ktm 450s? I have heard that the impeller wheel is too big for the hole in the case, supposedly boyesen was going to make the proper part but I havent heard anything else. It has always said it fits with the bike selected but like I stated I guess it actually doesnt until the impeller wheel is updated. I would order this right now if I knew for 100% certain that it fits

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.
