Hi,
I've just got an 97 2.5 V6 Manual omega and i'm impressed !

I'm thinking of doing some mods ! I've tried looking around for an induction kit for it but can't find one ? Anyone know where i can get one ?


Cheers
Joe

The general concensus is not to bother. The standard induction system is adequate and fitting cone filters and the like often results in less power and more noise as they pick up hot air from behind the radiator rather than cold air from the pickup pipe in front of it.

The oil used as a dirt retention agent in foam filters has also been known to contaminate the MAF sensor.

3.0 Cams, M-Tek Chip, Exhaust in Excellent Condition = whoosh in a 2.5, trust me

Steer clear of all that induction system rubbish, as Kevin says - you'll see a performance drop and some stuttering as it pulls red hot air directly into the engine.

I'm not sure about this.

I put one on my old Elite, it came with a heat shield & I used the original air feed pipe from the filter box which drew air from the front direct to the cone (I angled it so the pipe was touching).

I didn't notice any difference in temperature or performance (although this was after the hottest of the weather) just a deep loud growl under acceleration, not to everyone's taste I know.

I'm debating whether to put it on my new one  :-/

I think that's the point, Bo Bo. They don't make any difference in performance so it's down to whether you like the growl really. If I'm not mistaken yours is a 3.0 so one could certainly expect a 2.5 to breathe happily through the standard setup if there's no noticeable gain with a 3.0.

Also, the filter will suck air from all round its' circumference so it's still likely to collect warmer air. I found with my previous car when an air duct came loose that air from behind the radiator makes the engine seriously sluggish.

By all accounts the 3.0 cam upgrade is a must on a 2.5 though.  8-)

Nice quick, simple, SWMBO-friendly job too

I can understand that when the car is stationary for a while, but when moving with a direct feed from the front I would have thought the opposite. (Stands to be corrected  :-/ )

Its still going to suck from path of lease resistance, which may not be 100% cold air, unlike the standard setup...

"perfomance" filters give a psychological BHP boost; they make the engine note deeper (more sportier) and its "feels" or sounds as if the car is faster but it aint; and if not mounted properly the car will be slower (hot air).

I must say Bo Bo your old Omega (RIP) did sound good

Thanks people for the replys, I will leave it alone !

Kevin Wood did say about upgrading to 3.0 cams. is this difficult ?

It depends how much you have done before. It's basically equivalent to a cambelt change plus a rocker cover gasket change with a little more work added to change the cams themselves. ClarCE and I managed it in a day. Neither of us had tackled it before but we're both handy with the spanners.

It's a tedious job of dismantling and reassembly rather than being that difficult, although a couple of steps require a bit of care.

Using a cone filter will be perfectly fine if you build a sealed box around it and get a good air feed to it.

Personally, if you cant do that, use a good panel filter

Speaking of spanners, my 30mm deep offset ring spanner turned up today...

& so will the new one tomorrow  

I'm going to monitor the temp & see how it goes...
