(R18) Remove Coolant lines from the intake and increase horsepower.

[spinks]

This is a continuation of the extremely resourceful "DIY: Short Ram Intake for the R18 (Ghetto Fabulous)" thread, by Mikey6p.

This mod depending on if you are experienced with these type things should take about 10mins. for experienced, to an hour for somebody with the brain capacity of a brick wall.

Materials Needed
Small Filter (Red arrow)
Small clamp (Blue arrow) I got both of these at O'Reillys for $10.00

Saw, any size, should be sharp.
Pliers, preferably needle nosed.
Flat head screw driver.
Super glue (recommended but not necessary) [NOT HOT GLUE]
A vice will make things easier.
WD40
A drill, with a drill bit.
and a grinder will make things a lot smoother too.

Ok here we go.
Step 1.
Remove that big piece of crap that connects your coolant line to your filter.
Remove filter (Red arrow)
Remove coolant line (Blue arrow)
Remove engine adapter (Green arrow)

To remove these take needle nosed pliers to then metal pins. Pinch them and move them away from the hose. (When you remove coolant lines, any of them, they will spew coolant, don't worry it wont spit out all your coolant, get a cup unless you have some cleaner to spray off the coolant afterward)



Step 2. You will be utilizing this big piece of crap that connects your air filter to the coolant lines.
This is where the vice comes in handy. Put your big piece of crap that connects your air filter to the coolant lines in the vice in such a way that you can cut off these two pieces as much as possible. For this I used a saw that looks like this



Step 3. That Big piece of crap can now be discarded. The larger piece you cut off should now be smoothed off at the edges with a grinder such as this one. (This will make the next few steps much easier)


Step 4. Take the filter you bought, and carefully use a drill bit to make the opening of the filter adapter (Came on the filter, and is attached to it) slightly more hollow to fit over the adapter you just cut out. Use a very very small amount of WD40 on the outer rim of the filter adapter. Now slide the adapter you cut from the big piece of crap into the filter. After that slide the other end of the adapter onto the original rubber piece that is connected to the engine. If you don't have a pinch clamp for this (stock, I lost mine) Use the clamp that you bought with the filter. You are done with this part of the DIY. It should look like this.


Step 5. Take the smaller adapter that you cut out and smoothed with the grinder, and apply super glue to the first half of it. Slide that Adapter into either one of the remaining functional coolant lines, Apply super glue to the other half of the adapter and now slide the other coolant line onto it.

Make sure the now connected line is secure (I used electric tape) It should look like this

The blue arrow indicated a coolant line that is not connected to anything thus making it not functional, I hadn't taken it off when I took the pic.
The red arrow indicates where the coolant line used to enter the intake, but now they are connected without taking that detour.

MAKE SURE YOU CLAMP THE CRAP OUT OF THE NEW COOLANT LINE!!!!!!!!!!!!


The coolant that goes through the intake is actually a lot hotter than your intake. Taking it out allows more air into the car thus adding some torque and horsepower. When you drive it afterward you WILL notice the difference. Lmk if you have any issues or problems with anything in the DIY.

Wait a minute, did you super glue two of those rubber hoses together using a bracket and then tape it? You realize that there is a reason those lines are reinforced, because the high pressure over time will slowly ruin them, go spend 3 bucks and buy two feet of 3/8" transmission oil cooler or water line.

I wanna try this but is it worth it any CEL?

No I used a metal adapter, you don't even have to use glue, because the adapter holds so well, I just like everything extra secure. Also clamped it 4 times but dont have a pic of that

what if i already have a short ram intake, will this still work?

[AcurA289]

has anyone else tried this and noticed an increase in horsepower? just like hearing feeback from everyone before i tackle something

This doesnt add HP it will lower underhood temps as you have one less hunk of metal being heated up, any "feeling" of power is placebo.

[SI*DANNY]

what might you gain...
.1 hp and a lil lower engine temp
this is pointless and a waste of 10bucks
