just ordered some ebay headers. didnt realize they were for a 1.8. i have a 1.6. will they still bolt right on? and is the o2 sensor located in the same place on the header?

iToaster · 10-02-2009, 03:45 PM

The 1.8 has longer headers than the 1.6 due to the extra length of the block for the added displacement, so no, they will not fit.

I think they might be able to fit, but you need the bolt-on o2 sensor, not your stock screw in one. Try returning it and getting the right ones.

the problem is same
where to find the 2 bolt sensor

Ebay? Anywhere? There are only 2 kinds.... they are all the same, you should be able to find an O2 sensor in a store.... that is the easy part.

returned them with no prob. got the right ones. installing them Wednesday (hopefully)

great to hear! i hope you enjoy them, be sure to heat wrap them.

rubeq · 10-10-2009, 12:43 PM

should i wrap them bc i was reading that wrapping them traps moisture and in time rusts or cracks the header. i kno it doesnt require a heat shield bc of the lower temperature. and others said theres no need if im not turboing the car.

wrap is fine with stainless steel. mine have been wrapped for a few years and are just fine underneath.

rubeq · 10-10-2009, 10:17 PM

not to sound dumb but is the temp noticeably lower?

prizmster · 10-11-2009, 12:57 AM

does it add power? a lot of noise?

any engine lights after install?

thanks

i will let you know right after i install mine. and my engine light never comes on

Doesn't add much power, doesn't add much noise, doesn't through a CEL.

prizmster · 10-11-2009, 09:05 AM

gotcha. saves weight it seems mostly

hmm i'd argue against not adding power, butt dyno saw an overall gain on the 7afe with the ebay header. lost a touch of torque down way low, like idle speed to 2000rpm, but from 3500-6000 felt a strong gain. engine felt alot more torquey and responsive overall.
