    Does anyone know what wire this is that’s connected along with the MAF sensor connector? I saw the same wire on another car in a YouTube video but I know not everyone has it.
  2. Headers install stuck

    Articles - Engine, Core
    I’m installing my ktuned headers and I have gotten to talon out the heat shield and old headers. There’s not enough room so we were told to lower sub frame(not dropping it) we loosened the 3 bolts on each side and it hasn’t budged. Any suggestions I’d love the help. Edit: Ktunned header

  10. 4.7-4.3 Final drive

    Civic Si

    I am considering buying an 8th gen civic, but after looking at it I noticed that there was a fluid dripping from the back of the engine bay.
