2002+ 2.5L QR25DE XS Power Header and o2 Spacers Combo!
Install spacers as I ship them on last o2 sensor. No worries of the CEL doing header mod, commonly P0420 . OEM Pre-cat is a known engine failure sadly, Header mod is Best Bang for Buck for Safety and Power !
This does not touch the main catalytic convert that is mid car. 2004+ The 2nd o2 is on the midpipe, where 2002-2003 is on the bottom of Manifold/Header.
US orders only please, UPS or Fedex carrier service.
Must contact if outside cont. US.
*Canada / Hawaii +$35 shipping*
I have sold this product since 2003 w/ o2 spacer trick! Great Proven Header. Feel free to browse my response and online under MarkSpecV on numerous Nissan forums.
