API Intake Install - ZR-1 Net Registry Forums

LGAFF · 10-18-2015

Had this for awhile, I bought it with the flange broken off the neck. I never installed it as the neck of the intake turned out to be smaller than stock. So Today I got the heat gun and plastic welder out.

I cut the neck off a stock intake and grafted it onto the API reversed intake...now it should flow as much as stock and also pull denser air from in front of the radiator.

Need to do some engine cleaning...but hey its got 148Kmiles on it

This is not mine but this is what it looks like

Hey Lee,

Not too many of these around. I have one in storage, but did not notice that the opening was smaller than stock. That is some crafty work to modify that intake like that.

That looks like a stock airbox and an open KN type housing.

its facing down not up.....thats the difference

I've used one on my car for several years. Did not notice the size of the outlet. Since you have both Lee, what's the dimensional difference between stock and API? The stock airbridge fits prettty snugly onto the API, so size seemed to be the same.

Yeah I noticed the same as Dominic and I have had mine for years as well

Look at it vs Stock next time its off, the height is about .5" less and the radius of the ends is sharper.

The API plastic also has a lower melting point vs the stocker

Thinking about switching to Jerry's air bridge. Currently using the phenolic insert in stock airbridge but I think the thickness may be robbing some airflow capacity.

I need to switch to my samco air bridge
