HI all,
Finally got my BEGI airbox from protege garage this week, installed it on Thursday night, the entire job, took about 1 hour and it was so easy i have prepared a bit of a guide on how to do it yourself.. Firstly a review on the product.
The kit comes with a maf adapter a K&N filter, airbox and various bolts and screws... What it doesn't come with are instructions which is really ordinary as there are a variety of different screws bolts and allen bolts that you need to filter through and use in the correct application... As i am not convinced i have used all the screws in the right place i won't say which bolts are used where where i am not sure.
Temperature testing. Standard airbox inlet temperature was a consistent 24 degrees after driving the car for 30 minutes then leaving idle for 5 minutes to heat soak. BEGi box was tested after installing driven for 30 minutes and left to idle for 5 minutes and recorded an inlet temperature of 26 degrees celsius, Both were tested with a simple chemistry thermometer and should just be used as a guide.
Economy - Previously i was getting a maximum of 430kms to a full tank of caltex 98 octane mainly driven in light traffic and freeways, the car is pushed a few times each journey.
Since installing, After the first tank i saw 350km's out of half a tank, 521kms out of a full tank thats 171 kms more out of a simple intake mod. This could potentially be even more considering i was given the car a serve to hear the noise.
Performance -on WOT the TC is on permanently in 2nd gear and now comes on in 3rd in the dry, Traction will also come on in 3rd gear in the wet more frequently than before, car seems to be more responsive to throttle inputs ESPECIALLY in 4th gear.
Noise... By far and away the best thing... sounds wicked. thats all.
Anyway onto the guide... Firstly you need to take off the lid of the box and undo the inlet pipe from the maf housing. To do this simply unscrew the pipe connector, unclip the 2 clips holding the airbox down and slide the rubber slider on the guard side of the box backwards, you should also unclip the maf adaptor but at this point i would leave the maf unit still in the lid (for protection)... Now remove the top part of the airbox
Now take out the filter (it just lifts out)
the actual base of the std airbox is held in place by two rubber gromets, To remove the box, simply give the base of the box a decent pull and it will pop out.
(Pre work on the BEGi Box)
You will need to connect the max adapter, filter to the base of the box before you drop it in as you won't have the room later.
Now that you have done that, drop the base plate in and screw into place. It uses a std mounting point near the fuse box, simply unwind the bolt and re-use it after putting the baseplate in... (my baseplate required some filing to get it to sit flush)
Now remove the maf from the airbox and screw into place into the maf adapter that begi provide and push into the inlet pipe and use hose clamps to tighten. (note i could not use the std screws on the maf adapter i had to use bigger ones i had lying around as the mounting holes were too big, BEGi's production tolerances are not that great to be honest)
Now your ready for the lid, it attaches to the airbox and a mounting tab on the radiator support panel. Again i had to drill another hole in the lid of the airbox as there was no way the holes placed there by BEGi would have fit.
