Pictures are better hosted on the forum, not ImageShack, Photobucket etc.

Yes, they are available from Fiat.

Part number for the swirl plate is 71751469. Fiat say you also need two ordinary gaskets (part number 46773082) but I fitted just the swirl plate in my Stilo.

Blanked both my 2002 JTD and my 2005, I've did the 2002 after having cleaned the stuck EGR valve, the 2005 as a preventative measure.

The only issue I'm aware of is potential overheating, if you've got any data to back-up the power loss and mpg issue, I'd be very interested.
Most people have no problems and see a small improvement after blanking the EGR; Having seen the inlet manifold after the EGR had done it's job for 60K I'm convinced that while the EGR might reduce NOx emissions, it's not doing the intake system any good.
What's the point of having an airfilter and then feeding the engine it's own sh!t along with the filtered air?

I have two driving licenses, one photocard that cost me 35 quid, show it to the bobbies and they do~not~want~to~know. The plastic card was a requirement of Europe and / but / not required in this country.

The EGR was also [ Maggie Thatcher era ] a European diesel particulate measure imposed on all makers wanting to sell to the EuroZone. I do understand your sucking~your~own~s*ite point, but most / all bug users use the mod :

- to solve [ and it does ] a particular problem, and ;
- on motors that are usually well past their half life anyway

Greets momoe, just an - - :idea:
 
hi all,
i dont see the point in fitting a blanking plate thats full of holes, you might just as well not bother.:bang:
 
There's a moral issue as well though rick45, I prefer not to contribute towards pollution and prefer my EGR to be working as manufacturers specification. It's an age old argument (especially on this forum) and ultimately it's up to the individual.
 
Rick45,
the swirl plate was introduced as a remedy for EGR's becoming blocked.

By effectively reducing the diameter, the venturi effect speeds up the gas flow which deposits less crud in the EGR, general concensus is that it does work.

However, it's a retrofit and usually ends up being fitted in conjunction with the EGR being cleaned/replaced, would have been nice if Fiat had put their hands up and stated that the existing design was flawed and fitted this as a recall item.
 
Couldn't find a cost for the Multi, but the Croma swirl plate costs £13 which should be a good ball park figure.

Personally, I'd make a blanking plate and drill 3 6mm holes in it, you've got a picture in this thread for hole positioning, a couple of mil out isn't going to be critical.
 
Quite. If they're asking £13 for that, it's time to get the saw, drill and files out. It's coming up to EGR cleaning time for me in the next month or two, so I'll give it a go then.
