I have a stage 4 1380 fast road engine in building ATM I have a weber 45 score and will be on a maniflow straight manifold with weber box but what's the best air filter to use . Obviously you have k&n itg etc

[KernowCooper]

ITGs have a good report and easier to fit depending on the space remaining

[minilee94]

Okay thank you

[mingy]

I use an ITG setup on my 1380 with an HIF 44 and it goes brilliantly, give MED a call as they supply the right kit for the right carb, most F1 race cars use ITG filters!!.

[minilee94]

Ahh brill okay it may well be a itg one then I will call med tomorrow thanks

[minilee94]

Bloody hell med £200 for an itg set up I think I may just stick a big k&n on

Yes but you get all of this:

As i stated in my previous post i have an HIF 44 which has the correct ITG filter and stubstack that was purchased from MED for £90.00.
I do not know how much the ITG filter setup is for a Weber 45 but i would assume it is more than a single carb setup as you will need a larger filter media area and two stub/ram pipes for the Weber 45.
I originally had a 45 on my 1380 and in comparison the HIF 44 performs just about the same from around 3000rpm upto 5500rpm, above that the Weber just tips the scales but consumes far more fuel in doing so.

[minilee94]

Fuel is not a problem for me the car is a weekend toy . And yeah it's a touch more than a hiff 44 carb kit

And yeah I know you get all that but still steep for a air filter considering a k&n probs does the same

[Midas Mk1]

You asked for what's best, not what's cheapest...
Itg made a difference over the k&n on my hif :)

[minilee94]

Yeah I suppose I did ask best but still £200 for a filter I don't think I will be paying that .

I'm sure there are other filters just as good but cheaper

[custodia]

i use the k&n like this one -

on my weber 40 dcoe. Fits lovely and is recommended in the a-series bible although itg weren't around then.

[Spud_133]

If it was me, I'd use the ITG, you've already gone for the more expensive option of the weber over a hif44, and the rest of the build is top spec, so why not going for a top spec air filter?

What does "stage 4" engine mean?

[waldofski]

The ITG filter, would that fit on with the short maniflow manifold without any bulkhead work?
