I would rather get rid of the stock casing and have a cone tbh, so I agree with you. I think that's the way I'll go, but I would have preferred a blanking plate to ensure cool air.

Keep the original airbox and fit an induction kit into it then remove the resonator and fit the intake pipe from a GTA (search the forum for GTA mod). The reason for keeping the original box is to drastically reduce the risk of hydrolocking the engine. You're also best to use a non-oiled filter as the oiled ones can kill your MAF. Many of us have used the Apiro Torque universal filter from Regal Motorsport, it costs peanuts and really does work.
There's a great thread about it in this lounge, I'll dig it out and post the link...

I hadn't read this before I did my last post, so thanks and I will take your advice.

Here's the link to the tread I mentioned..

There's also instructions on the GTA/V6 mod in there somewhere too.

Cheers for this and I will bear it in mind. I run oiled filters on my Volvos, but have to be very careful to not over oil, and have so far managed not to jigger a maf.

You can remove the MAF and fit the filter, take the car for a 20mile blast and it should suck the excess oil off.
Don't expect power gains though, what you do get it improved throttle response, especially mid-range, better noise and you don't have to struggle every year to change the standard filter.
If you read through the thread you'll see I was a skeptic to begin with but I took the plunge and think its a worthwhile mod.


Oh, and I'm getting 2mpg better fuel economy since fitting it and the old filter had less than 1k miles on it...

Right, applied WD40 to the 3 airbox nuts and just tried them. 2 came out with no problems with a 7mm socket, and they 3rd has crumbled away. Therefore, that has steered me towards getting rid of the original airbox, and fitting an induction kit.

I will speak to BSR whom I normally use for the JR gear, and if they haven't got a kit for this car, then it'll be a K & N.

The Apiro Torque filter fits on top of the airbox perfectly and the airbox with the V6/GTA mod feeds it cold air, so no need to remove the original airbox....

 

[Tommywho156]

Have you got a link or more info. on this filter please?

I'm out at the moment but there's info in the thread I posted the link to earlier in this thread mate...

 

[Tommywho156]

I thought you had. Thanks, and they go on 'the list' as well. I would want to remove the old airbox, just to make the space and look tidy tbh.

The link in that thread is dead, it appears Regal Motorsport is out of stock. I found them elsewhere though..

The reason for keeping the airbox is mainly for reducing the risk of hydrolocking the engine as the filter is pretty low down and at risk of water ingress. Mines fitted inside the airbox and it works a treat...

 

[Tommywho156]

The Apiro filter mod only works if the airbox top can be secured properly, in this case one fixing is not serviceable so the filter would be pulling hot air from the engine bay. Not ideal!

Nope. The Apiro fits and rests perfectly around the airbox rim, there's no need to secure it, the airbox itself holds the filter in place...

 

[Tommywho156]

Hey? The new filter fits to the little jutting out bit of plastic tube on the box lid. You don't then secure it at all? What if it falls off?

Lol!....No, it connects to the MAF and then the cotton/gauze lowers into the airbox, the silicone base of the filter is a slightly larger diameter than the hole in the top of the airbox and fits snuggly enough to hold it in position. I've had mine on for a couple of months now and covered a few thousand miles over some pretty crappy roads and mine hasn't moved at all in that time and I check it weekly when I check the oil, coolant and tyres.

All becomes clear, I am clearly slightly thicker than enough!

Lol, nah. When Grahameo first described it to me I didn't quite understand it either it is, afteral, quite an unusual way to mount an induction kit. Works well though.
