  • Vehicle power must remain between 11.5 and 15.0 volts
  • Parking brake must be applied
  • The transmission must be in Park or Neutral
  • Glow plugs must be off

    does the job

    nice product. easy install but i used a dab of silicone grease to keep the o-ring on. wouldnt have needed it if the intake spider was off. the only thing is i had to go find another sized socket to install since its bigger than the 1" intake heater this replaces. also id find a 90dg fitting for the boost gauge line so your boost line isnt bent out in the open.

    Easy install, looks awesome, increased air flow by obvious reasons, fast delivery plus got a sticker!!! Not sure if it gives me more power but I don’t care. It has to help.
