Time Required
Absolute minimum 1 hour, but more likely to be nearer 2 or 3 if you're on you're own and have some seized bolts like I did.
Tools Required
Jack
Torque wrench
Various screwdrivers
Angled screwdriver*
Various spanners (small handles help in accessing tight spaces)
WD40
Glue for sticking plastic
1 Cable tie (there might be one provided, but mine was missing)
Air filter oil (buy this when you purchase the Hurricane)
* - There is no way you will be able to access the MAF sensor without an angled screwdriver. The coolant tank is in the way. The Hurricane instructions do not mention this.
Oil the filter
The filter does not come oiled. Remember it's the oil that keeps the crap out, not the filter itself! Oil the filter with the spray as instructed on the can. Leave to dry for around 20mins while you start the installation.
Remove Sensors
Follow the Hurricane instructions for removing the two sensors (the top one is actually a vacuum solenoid). However, note the following:
- You don't need the top one (solenoid) after fitting the Hurricane. It simply opens a flap on the existing airbox
- The screw holding the solenoid to its bracket may have seized up, so be careful not to snap the solenoid as I did when removing. You may want to put it back on some day if you fit the original airbox back on.
- Let the solenoid and its associated electrical connection and hoses dangle around at the moment. You can tuck it out of the way when you're finished.
- You will need the angled screwdriver to access the MAF sensor.
- Be careful not to drop or damage the MAF sensor, but you may need a bit of effort to disconnect it from the plug (you must squeeze the plug to pull it out)
Removing the airbox
Do not follow the instructions here. They claim that you can remove the airbox without removing the wheel and arch liner. This is nonsense!
First, undo the clips that hold the existing hose going from the engine to the airbox and remove the hose. This might need a bit of effort as the hose is quite stiff rubber.
Jack the car (insert usual warnings of jacking safety here!) and remove the nearside rear wheel. Remove the wheel arch liner. Note that there are several more screws in the arch liner than the Hurricane instructions claim.
You can now see the airbox from underneath and you should see the metal clips that hold both halves of the airbox together. Unclip these and remove the half of the airbox nearest you. The existing filter will probably come out with this half. If not, pull it out of the remaining half.
Observe the lovely crap and dead flies in your filter!
The snail-formed induction pipe should come out with this half of the airbox.
You'll now need a spanner to undo the 3 bolts holding the other half of the airbox in place. On my car (under 2 years old), these were very tight and required a lot of effort to undo. They're in a very awkward place. This is where the WD40 might come in handy. With a bit of effort, you should get them off.
When pulling out the two halves of the original airbox, you'll notice that they're attached to the vacuum hoses that come out of the solenoid you first removed. Just detach these from the airbox and leave them connected to the solenoid.
Go and have a cuppa - you're around the half way mark
Fit the MAF sensor in the adaptor
Follow the instructions provided here, but note the following:
- If you fit this tight against the adaptor just now, you won't be able to get the plug back into it when you fit it back on the car! Just tighten the screws enough to stop the spacers falling out for the moment, but do ensure you've pushed the sensor right inside the tube.
Fit the adaptor and MAF sensor into the air box as instructed.
Fit the induction scoop
Follow the instructions here, but note the following:
- Do not tighten the bolt too tight when fitting the air vent adaptor, as it could crack the plastic.
- Do not stick the little plastic flap onto the air vent adaptor with the provided double-sided tape. It's rubbish! Stick it on with glue! However, do use the tape to stick the other end of the flap to your plastic side grill as you probably don't want to fix it to that permanently. You'll probably want to clean the grill first so that the tape sticks better
Fit the airbox
Follow the instructions for this (top of last page), but note the following:
- You have deliberately left the MAF sensor screws a bit loose as instructed above so that you can fit the plug back in
- Squeeze the plug back onto the MAF sensor carefully, but make sure it's on firmly. Then tighten the screw that hold the sensor in place
Fit the induction hose
Follow the instructions, but remember that the plastic tape will not hold it onto the air vent adaptor on its own. You may have been provided with a cable tie, but if not, you'll need one. Use the cable tie to firmly hold the hose to the plastic air vent adaptor.
Finishing off
- Make sure all clamps/ties/connections are nice and tight.
- Put the wheel arch liner and wheel back on. Remember it's 105Nm torque for the wheel nuts.
- Cable-tie or tape the vaccum solenoid and associated hoses out of the way, closing off the ends of the hoses with some tape so that crap doesn't get in them (in case you ever want to refit the original). You can actually fit the solenoid back on its clamp and attach it to the ECU box to keep it out the way. Mine is just cable-tied onto the old airbox mount.
Finally, enjoy!
Find yourself a nice stretch of road, put the foot down to open up the throttle and around 4.5 - 5k revs and higher, you'll hear a lovely roar! When the 2nd cam kicks in, you'll think you're going to take off! 
As good as you hoped
