STAGE ONE: RE­MOVAL OF THE OEM IN­TAKE

1. Be­fore any work can com­mence, the bat­tery neg­a­tive needs to be dis­con­nected. NOTE: Dis­con­nect­ing the neg­a­tive bat­tery ca­ble erases pro­grammed elec­tronic mem­o­ries, so write down all mem­ory set­tings be­fore dis­con­nect­ing it. Some ra­dios will re­quire an anti-theft code to be en­tered af­ter the bat­tery is re­con­nected. This code is typ­i­cally sup­plied with your owner’s man­ual. If your ve­hi­cle’s anti-theft code can­not be re­cov­ered, con­tact an au­tho­rized deal­er­ship to ob­tain it.

2. Dis­con­nect the mass air­flow (MAF) sen­sor con­nec­tor, and un­hook the wiring har­ness from the air-box.

3. Us­ing the pli­ers, re­move the two spring clamps and dis­con­nect the crank­case vent fit­ting from the in­take.

4. Use the Phillips screw­driver to loosen the hose clamp se­cur­ing the in­take hose to the throt­tle body.

5. Use the screw­driver to loosen the hose clamp and dis­con­nect the en­gine sound tube from the en­gine sound drum, lo­cated on the right side of the bay.

6. Re­move the three bolts se­cur­ing the res­onator and air-box to the core sup­port. NOTE: These bolts will be reused in a later step. Re­move the en­tire assem­bly from the ve­hi­cle and store safely in case you want to re­vert the mod­i­fi­ca­tion come sale time.

STAGE TWO: IN­STAL­LA­TION

7. Us­ing the fac­tory hard­ware you just re­moved, in­stall the provided heat-shield mount­ing bracket (070026) onto the lower air­box mount.

8. In­stall the provided three-inch to 3¼-inch sil­i­cone hose (08186) onto the throt­tle body and se­cure with the provided hose clamp.

9. Prep the heat shield by ap­ply­ing the two in­su­la­tion strips onto the bot­tom side of the shield. Trim to fit.

10. Three brack­ets need to be in­stalled onto the heat shield, as shown, us­ing the provided hard­ware — 083170, 070066, and 070015. (070015 uses a provided spacer and will need to be left loose for the time be­ing.)

11. The last ad­di­tion to the heat shield is the edge trim. Cut into two pieces, one 685.5mm and the other 330mm. In­stall onto the ex­posed edges, the longer piece go­ing along the top and the shorter piece around the pre-cut hole.

12. Re­move the core sup­port bolt shown. NOTE: This bolt will be reused.

13. Bolt the heat shield into po­si­tion, us­ing the fac­tory air-box mounts and the core sup­port bolt you just re­moved.

14. The next step is to prep the K&N in­take tube for in­stal­la­tion. First, thread in the plas­tic 90-de­gree crank­case vent tube, be­ing care­ful not to cross thread. In­stall the vent fit­ting hand tight, then turn it two com­plete turns with a wrench. 15. Re­move the MAF sen­sor from the fac­tory air-box and in­stall it onto the K&N in­take tube, us­ing the provided hard­ware — not the fac­tory bolts. 16. In­stall the K&N in­take tube through the heat shield, be­ing care­ful not to dam­age the edge trim as it’s a tight fit. You will also need to in­stall the provided rub­ber mount be­fore ro­tat­ing into place.

17. In­sert the in­take into the throt­tle-body sil­i­cone joiner and tighten the provided hose clamp. En­sure the rub­ber mount slots into the loose bracket in the heat shield. Tighten ev­ery­thing up.

18. Con­nect the crank­case vent hose on the el­bow and se­cure with the OEM spring clamp you re­moved ear­lier. You will also need to in­stall the provided Caplug onto the en­gine sound drum, and re­con­nect the MAF sen­sor con­nec­tor.

19. The fi­nal step is to in­stall the K&N air fil­ter and se­cure it us­ing the provided hose clamp. En­sure that ev­ery­thing is tight, and re­con­nect the neg­a­tive bat­tery ter­mi­nal.

Added Pro­tec­tion

As added pro­tec­tion for your fil­ter, a Drycharger air-fil­ter wrap — Part No. RC-4630DK — can be pur­chased in a num­ber of colours.
