CAI Are Bad News!!!!!!!!

By that logic, the NST throttle body spacer would help also, right?

 

I understand that... but the spacer would put a larger volume of air after the butterfly valve, meaning it's more readily available for combustion. That being said, it seems the problem is more the timing on the butterfly valve vs. the placement.

 

No. The NST intake port spacer (not a throttle body spacer) effectively lengthens the intake runners. It worsens throttle response by a very small amount because the air volume downstream of the butterfly valve is increased. Remember that volume is evacuated when the throttle is closed. When the throttle opens, air has to fill that volume before reaching the cylinder.

 

I see... so this goes back to another post someone made about Ferrari's method with the adjustable runner. Ideally, that's how you get the best of both worlds.

 

I just started this thread to see if anyone had bad experiences with a cai(or in our case different filter) and so that people would acknowledge that they should be concerned before spending 400$ on a "Cai".

 

You need air readily available before the butterfly valve, and as little volume as possible after.

Adjusting intake runner lengths isn't as much about throttle response as simply getting a good powerband. Air has mass and inertia. Longer intake runners = more inertia, so it's suited for low-end power. Shorter runners = less inertia, so it's suited for high-end power. IIRC the NST spacer gives you about 5 extra hp at low rpms and 5 fewer hp at high rpms, so it's a compromise. Before Ferrari's system, there have been cruder systems like Mazda's VRIS used in the 626 and MX-6 2.5L engines, where it switches between two intake runner lengths.

Chrysler does this on their current Hemi manifolds.....

 

Yep, as time goes on, technology becomes cheaper. Mazda's VRIS is from 1993, by the way.

Hi all.

I won't get into the paper is better than oiled argument - but ...

I owned a '90 gixer 1100 for 15 years. Bought 'er new and after the first year I removed the airbox (with its OEM paper filter) and went to individual (oiled) K&N's mounted right on the carbs. This was done with the stage 1 induction kit and header. This bike saw redline operation daily. Over 500 street drag runs. After 40,000 km I finally went to the track. Raced 3 years and got 2nd in pro dragbike 2 years in a row, at my local track.

After the first season at the track I tore the engine down (myself) and freshened it up - new main bearings, new big end bearings, undercut the upshift side of 2nd gear dogs, etc., etc.

Point is the cylinder walls and piston skirts looked like new - I mean not a mark on them. Now whether this is because of the K&N's filtering properly or because of my fanatical maintenance schedules ( my buddies always joked that the oil I drained looked as good as the oil I refilled with, during services) is a matter for debate, but the oiled air filters were doing a good job for sure.

Just my 2 cents ...

Cheers
Ray.

 

Sounds kinda like a fake non functional hood scoop

 

Sooooo....get a cold air derp or no?
I'm more confused now.
Or just a TRD one...
Or a dry drop in...
Or a lubed one...for her pleasure.

 

Same as the Fram I just bought.

Just did a 7h offroad trip on some insane dusty gravel roads. Caked the one i had put in 6 months ago. There was a little dust on the inside too so just bought another.

There only $25 so its not a huge deal. I change about once a year or when needed.

$16 plus shipping for OEM.

And yes... that's how I view it.
$55 for a K&N, that's already 3 years worth of filters.

Then every 20-30k or so, it's the cleaning ritual... and the inevitable...
"No honey, I can't go to the store to get you more tampons because my air filter is still drying so I can't drive the truck"


And getting worse filtration on top of that.
I'm really looking forward to the new pics from the conventional filter compared to the K&N... but I already have used oil analysis reports from my motorcycle that tell the K&N story.

 

Wait...was that a pro or a con?

 

Haha...I was thinking the same thing.
Plus, I think Rich is the last person on this site going to get tampons for wifey...after me.

 

That was only an example.
