are they any good? :-?

[Marks DTM Calib]

Nice easy one this....nope.

They only add noise and often lower bhp

?? I know there're shit but how do they make it worse?

[Lazydocker]

Because they suck in warm air

Oh... and if it's an oiled type it'll probably trash the MAF sensor too

[feeutfo]

No, pikeys only....

The whole setup on the cars is designed and tuned to the engine characteristics. They spend a fortune on modeling and measurement to get it right.

You then get an induction kit chucked on, with a filter which most likely has a smaller relative surface area plus a setup which most likely draws warmer air into it. Most of which are in reality fag packet designs based around 'what was done in the past on different units'.

The result is, poor operation.

Years ago, in the days of the pancake air filter setup and carbs then yes, an induction kit worked. These days, they do nothing more than increase the noise and often restrict the output.

And there are loads of real tests to back this up

It does really depend on the type of induction kits your after?
If your thinking cone, don't bother, waste of time, and you lose about 10% of your engine power.
They do sound good though, but thats about it.
I have found with my mv6 that a direct cold air feed is best.
I removed the standard little plastic air feed that sites behind the grill, and put a larger hose from the lower grill directly into my air box.
That combined with a pipercross panel filter works alot better.
The other option that is out there, is a pipercross viper kit, but that does cost in the region of £180.

i was always a bit dubious bout induction kits, thou the cold air feed sounds intresting

    Got any piccies?

[steverubberduck]

I haven't got any pics of the air intake....
But basically, if you take the grill off and look behind it, You'll see the air intake, it doesn't collect direct air, as it doesn't face out.
So all i did was remove this part, and buy some performance hose, halfords sell it, or buy online.
All i did then was attach one end the hose to the back of the lower grill, and the other end directly into the standard air box.
So now, when you open the throttle, you can feel the cold air being sucked in from the lower grill.
Doesn't make any sound difference, but you can feel it.

thats a damn nice set up.

is it just me or is there too much coolant in your resevoir?

[steverubberduck]

i was flushing the system....
trying to clean the header tank

Induction kits vary in performance depending on the car fitted and where they are mounted within the engine bay.

On a V6 Omega they are useless as a standard replacement because the engine bay gets too hot due to poor air circulation and the fact the filter is right behind the headlight so no cool air coming from the front. This can however be rectified by modifying the existing air box too house a cone filter inside and then bin the standard air intake and replace it with a bigger one this will give a pretty good increase in power probs around 4 or 5 %.

The viper induction kit already mentioned works well but is pricey.

On the whole in most circumstances a good induction kit will give much better performance than  the standard set up. I gained 9 bhp on my alfa sportwagon by fitting a K&N kit.

Ignore all the pish about the car makers tuning engines for best results, there all tuned to keep the bill oddies happy and save the planet not too give best performance. Most modern cars can gain upto 20% power with out changing any engine parts by simply making them breath freely with an exhaust, induction Kit and remap.

        Thanks for that Steve .

  What size pipe(ID) did you use?
