**Now included: 1 x 90° 1/2" NPT to 5/8” hose barb, and 1 x 1.00” hose clamp**

Our K20Z3/ K24A2 water bypass adapter allows RAA, RBC, RBB, and RSP cylinder head owners to run the more popular aftermarket intake manifold options that were designed for the earlier PRB/ PRC flange. The PRB/ PRC style manifolds do not have an integrated coolant passage so the coolant bypass hole is left open when used together. 

Even if you don't plan on running a PRB/ PRC style manifold... there are plenty of benefits that make this product a must have! The biggest benefit is in the reduction of intake manifold temps by eliminating the heat transfer/ heat soak associated with hot coolant running through the manifold. By modifying the manifolds flange (cutting off coolant portion) and running our adapter the coolant is kept away from the manifold completely, just like what you would find on the earlier PRB/ PRC heads, so NOW your Hondata IM gasket will really work!! We've seen drops as much as 18°!! Not to mention, the additional benefit of no longer having to drain the coolant when removing the intake manifold for maintenance or swaps... makes things a real SNAP!

 

We recommend a TracTuff Bypass Hose Fitting when connecting the OEM bypass hose.


Installation Guide

 

 



 

 

Start by selecting one of the two o-rings (one is a back-up) and install it into the recess on the adapter’s backside. Set the adapter aside.

 

 

 

 

 

 

 

 

Grab the stainless steel link and longer 40mm Genuine Honda flanged bolt and install the bolt into the smooth hole in the link.

 

 

 

 

 

 

 

 

Install the bolt and stainless link into the right-most intake manifold flange bolt hole. Tighten lightly with the link facing upward.

 

 

 

 

 

           

 

 

Grab the shorter 28mm Genuine Honda flange bolt and adapter and install the bolt into the lower bolt hole.

 

 

 

 

 

 

 

 

Take the bolt and adapter and install it over the exposed water & egr ports. Thread the bolt into the cylinder head until it is hand tight.

 

 

 

 

 

 

 

Grab the stainless steel set screw and thread it into the stainless link. The pointed set screw will tighten into the hole well but in some extreme cases it may be a good idea to use some medium grade Loctite.

 

 



 

 

 

 

 

Swing the stainless link and set screw down until it lines up with the pilot hole of your choice.

 

 

 

 

 



 

 

Tighten the 8mm intake manifold and Water Bypass bolts to 18 lb. ft. of torque and tighten the set screw until you have sufficient crush on the adapters o-ring. Congratulations! You're done.

Great busy toy!
Color: Squirrel
My dog loves this toy! And I hate squirrels, so I love to see him try to k*ll it. Haha Some of the "pockets" are a little deep and he did manage to rip 1 pocket off during the first use; but it's still keeping him busy!

Velcro for folding?
The toy came folded in a bag very nice. However once I took it out I realized the folds were attached by Velcro. Once unrolled I have not needed to use the Velcro since. Just one piece of the toy that was unnecessary. Otherwise t the dot is very colorful and my dog has not been able to tear it up yet.

Great toy for moderately destructive dogs
Color: Dragon
My dog LOVES this toy. It's not hard to see why: it has just about everything a dog could want in a soft toy. There are ropes that move around, a squeaker, crinkly wings, and different textures of fabric. It's not extremely durable--I've had to sew up one busted seam within a month or so--and you will likely have to re-knot the ropes and pull them back through the holes, but if your dog is only moderately destructive, they will enjoy this. I'd buy another.

Dog Obsessed -- Toy a Mess
Color: Squirrel
The dog was OBSESSED. Truly loved this toy, but he ripped the little pockets really easily. While he still wanted to play with it, it was a little disappointing.

Cute toy
Color: Squirrel
My dog loved it! Looks just like the pics. Durable for most dogs I’m sure. My little dog can destroy anything though lol! Didn’t get to use the treat part cause he destroyed it but looks like a neat concept
