Default ACKNE - Aluminium Custom K&N Enclosure for the Safari!!!

Yet another 'nikki special'!

We've been planning to put the K&N conical filter back on the Safari with a similar sort of enclosure as the Green Cotton (+Dynasomething kit) to reduce the intake noise that was its bane.

Finally Chikku (nikkibike) decided to do something about it and in his usual style he started planning this thing in great detail. We initially considered making a fibreglass enclosure but his dad adviced against it saying that it would crack after a while.

Those words couldnt be truer, because the Green Cotton enclosure cracked last week and the Safari gave the ominous "Engine Check Light" which was traced back to the air intake which had come loose after the Green Cotton casing had cracked.

Good enough excuse for Chikku to speed up the development effort on the new enclosure, for which he had chosen aluminium!

Here's the end result which will go into Dicor 9800 tomorrow! Comments, please and a HUGE thanks to Chikku for his meticulous craftsmanship:

Lovely Lovely Lovely!

Just get the casing burnished or sand blasted or something - will give it an even finish - make it look even better!

The finish is really good. One doubt though. The height of the filter and the centre cylinder seem to be identical. If that is the case then when you assemble it up the airflow into the filter will be restricted i.e. may get choked. I may be wrong, since I'm just seeing the pics. any pics of the top just before putting on the upper cover.

We may need to put some rubber or other beading where the cone meets the two other sections. Knowing nikki though, he would've thought about it already.

I may be wrong, But wont this effect the temperature of the Air that wil go into the engine? In lay mans terms, Wont the Air be hotter than usual, thus decreasing performance.

The plumbing from the Green Cotton kit will be retained and the inlet will therefore take air from the grille.

Unless you're referring to the use of aluminium, which will take heat from the engine.

im guessing he is talking about the aluminium which will absorb heat from the engine.

Well..I dont understand why the filter needs to be covered ? I think the noise factor is based on the plumbing lenght after the filter into the manifold!

Neat and well executed.. but this makes me think.. Does a conical filter have more surface area than the OE replacement filters? If not will this setup be more efficient than the OE replacement setup with modified ducting to ram in more air??

If that were the case, I would have had the same inlet noise with both the OE filter (which was fitted back with the same K&N plumbing) and the Green Cotton which was again fitted on the unaltered K&N plumbing. I havent had inlet noise with either, so I dont think that is the case.

Still, you never know until you actually try it on. I guess nikki will post the results here later today.

Thumbs up Cool stuff

Very very nice fabrication, especially considering its sheet aluminum.

Could we have more pics of the fabrication please ? Especially the conical section A list of parts & materials used would also be nice

One could possibly nickel plate the enclosure & cover it with header wrap.
