Hi,

When I bought my 156 1.8TS it had a bolt on K&N filter.

I want to put the standard airbox back onto the car and have been offered one from a 2.0TS, the box going into the front wing is still there its just the airfilter box and pipe to the MAF that I will be refitting.

Could anyone confirm that it would or would not fit as it looks too big to put into the space that is there because of the radiator pipes, also the body attaching fittings seem to be in a different place too...

Any help would be great.

2.0TS & 1.8TS 156 use the same air filter housing.

Yep it's complete git to get out. I broke the cover on my 2.0 TS just trying to get the lid off to change the filter. Spent ages trying to get the whole thing out to repair it and eventually gave up and bodged it with duct tape.

However, 100% recommend getting yours back to original. Unless aftermarket filters also have air ducts to draw in outside air from the grille area (rather than from the hot engine bay) the ECU will be working off outside air temperature but the engine will be drawing in air from the Sahara.

...the ECU will be working off outside air temperature but the engine will be drawing in air from the Sahara.

The ECU reads the intake air temperature in the MAF sensor.

So that's outside air temperature then (if the intake is in the grille), not engine bay air temperature (if the intake is in the engine bay).

It is the temperature of the air in the air intake.
Not outside temperature and not engine bay temperature.

I thought that the technical point was that a K+N filter, which clamps directly onto the MAF, draws in hot, low density air from the engine bay. So any debatable power gain from an increased air flow filter is more than negated by the fact the air is hot. By definition the best air or fuel for any ICE is the coldest you can get, hence chilled racing fuel tanks etc. Cold air = more air =more fuel = more power. The good Mr 'chappers' appears to be fully aware of this or he would not be binning the pointless K+N in favour of the standard setup ?

I just had the pleasure of taking out the airbox in order to repair the broken screw threads that had completely rusted off. To do so you to remove the battery tray (4 x 13mm bolts with one under the plastic undertray). You can then wiggle the box out once you have managed to press in the 2 plastic "tangs" holding it to the outer airbox.
Having cut of the tops of the rusted screws I then proceeded to try to drill out the remaining metal. Not too easy as the metal is pretty hard and the drill soon went off centre. Anyway I managed to get a 4.5 mm hole partly in the brass surround and then tapped out to take an 8mm bolt (x 3 of course).
Refitting is the reverse procedure as they say but you have to align the outlet from the box into the outer airbox whilst also getting the plastic locating pins in the bottom aligned.
It's a nice feeling to have the airbox functioning properly again but I wouldn't call it easy.

Tried to get it in earlier and was stumped how to...

Had the battery out, top radiator hose off and still couldn't wiggle it into position. Was just going to ask on here what was the easiest way to get it in (through engine bay or front wheel arch) but thanks to 'Doug164' looks like I found the answer. Battery Tray Has To Be Removed.

Will have another go tomorrow.

Thanks Again All!!!

Junk the resonator box in the inner wing .. replace it with a V6 or better still a GTA intake pipe ....

Gazza,
What are the benefits of doing as you suggest ? Also what are the costs - are these bits available secondhand ??
