Correct!

I doubt I can fit 3 sensors in the collector proper. From photo's, it would appear that mounting a sensor (any) in the top/vertical location is constrained by the firewall/tunnel. Is there any reason anyone can think of that would prohibit placing a bung/sensor in the flex pipe itself?

Excellent. So I will need to measure the current length and add 1".
Thanks!

do you have a PZEV car with the air injection rail in the exhaust manifold?[/QUOTE]



nope have a nonpzev but i only have two sensors so i leave alone the first o2 bung thats correct? and i should only put the 02 sensor in the next bung and the nonfouler drilled and one undrilled in the last 02 bung?

for what it's worth........I couldn't drill through the damn fouler, and when I got close I'd heated the thing up so much that all of the metal that came off of it got stuck on the threads and stayed there XP.

Anyone know if the long/deep foulers would fit our 02 sensors?

btw for what it's worth....... I've now been running for two days with an open header, first 02 wrapped around a hose in the engine compartment (the first 02 bung faces DIRECTLY toward an alternator stud. DAMN IT.) and the second 02 is just screwed in to the last hole on the header. no cat either. BOY is it loud but you know what? NO CEL! wtf. lol.

I have a SVT longtube header, im throwing a CEL for my front o2 sensor,I also have a wideband installed in my rear o2 slot, would this work for my front o2 sensor?

[aviationmech406]

ok sorry for this but just checking, can i use a bung on the first o2 of a header for the svt? idk whats going on but ive been through 3 o2s this last year, same cel code to. i was thinking maybe mine keeps getting fouled up idk. thanks

I have a zetec and i am installing a focussport header. is this going to work approximately the same way? I could not find another how-to for this
