Im trying to find info on the 2005 LH6 intake . Im going to call this intake a Tweener because it is in between years, old vs new style. Its a old style intake with a 4 bolt 87 mm tb. part # 89017588. From what I found it was only used on GMT 360/370 platform in 2005. In 2006 they went to the TBSS/NNBS intake. My question is does anyone have a 2005 Trailblazer or Envoy that came with the TBSS intake on it ?
