hello all, before i start this is my first thread which involves pics.....
As you are aware i make a topic called green cotton vs kn induction and now i have my kn fitted i thought id show you all hows its done. even though its the same as fitting a green cotton but ive done thing else to the system. To aid the induction i have also removed the snorkel that starts from the right hand side of the car and goes to the air box. i have many pics so please feel free to comment and ask questions.
firstly i gained acces to the airbox.
next undo the four bolts that hold the airbox lid on to the airbox structure.
now at this point the lid will pull away and you will have acess to the air filter.
Now what i did at this stage was I removed the securing securing screws that hold the grill to the car. There is a reason for this and ill show you.
To improve futher airflow to the airbox further i removed the snorkel which was the reason why i removed the screws for the grill to gain access. In the next picture you can see that i have unshipped the grill and the top plastic cover which covers the snorkel. i didnt remove the grill i just lossened it as i wasnt too sure on how to remove it. i didnt want to make too much work for a job that take around ten minutes also if you get me......
once the access was there i removed the snorkel. this is easy but it doesnt come straight out. you have to weave the snorkel out towards the right of the car (left as your looking at it) due to the bonnet lock being in the way but its easy to remove the snorkel. Once removed refit all the securing screws to the body work and now filter fitting time.
here is the old filter(well new as the car has just been serviced)
and here is what the standard filter looks inside.
while the airbox is empty give it a good clean. remove the box if you have to... its held down with two rubber mounts... remember to remove the breather pipe before hand otherwise you may inflict damage to the breahter pipe.
Anyways here is the k&n filter in hand wrapped up. Good ebay bargain. arond 37squids brand new. part number if anyone wants to know is E-2993.
they dont come oiled so clean and oil your filter before install. for this purpose i havent oiled it due to showing you peeps how its done.. anyways here below is what it looks like fitted in the engine bay.
Here is the k&n filter internals.... looks alot better than the standard filter dont you think?
here is the difference between the two filters. what i didnt know was that the filter is slightly offset.. dont know if this is the same with the green cotton filters....?
once your filter is installed into the intake pipe make sure you line up the plastic disc at the end of the filter in the grooves otherwise your top filter housing assembly will not fit correctly and will not sit. refit the bolts that you removed on removal and remove all tools from area.
now start your engine up and give it a whirl.
what i found was that there wasnt alot of difference when the engine had know loads apart from the noise. well you can here the turbo spool up abit louder . but when your out driving there is a good difference. the responce is improved and i think with that snorkel removed there is much more air for the enigne to suck in and with thatshort scoop your left with when you remove the snorkelacts as a ram and it does make a difference.
i also tried it with the snorkel back one. but ive decided that its staying off as its not doing any favours to k&n....
i have written done my fuel consuption and then in a months time ill see if there is any difference and by then that will give the ecu a change to adjust. my MPG is 60.7 and thats with normal driving motoway and town driving....
anyways i hope you have enjoyed this and i hope that this will help you decide to either go for k&n or green cotton.
one last thing remember to look on ebay for bargins..
