Astra H 1.9 CDTi Simota Air Filter

[Baneofdecay]

Did you know that most VXR owners replace the VXR air filter with the one from the 1.9 CDTi as its much much better. All you might want is to replace the pannel filter with maybe a K&N pannel filter. If i was you i would get that simota out asap.

[hdrahic]

Where u put intake ? is that 1.9cdti 150hp? Because i dont have any space for air filter intake like that

[kotanidi]

hi, and i have opel astra g but where is cabin filter?

[khisanth75]

Have seen many tests and the ones where they kept the stock box and filter did best. 2nd was drilling some holes in the airbox!

what bhp u got?

[Stagobos]

where did you get it? this engine type isn't on the simota website

[XGallowsX]

makes it hiss more??

Surely a race filter only makes a difference at wide open throttle?

[OneLifeLiveItNow]

A diesel engine does not have a throttle. It is breathing at "wide open throttle" (petrol engine equivalence) ALL the time. Diesel engines are always lean burning, which means that fuel to air ratio is always below stoichiometry. Engine power output is solely controlled by the amount of fuel injected near piston top dead centre. Low restriction air filters help improve engine breathing at all rpm.

There are some diesel engines that have semi throttles. That's to induce turbulent swirl.

Cheers.

There is a tiny tiny fraction of petrol (gasoline) engines that do not use throttle plates to throttle the air, but instead rely on the degree and duration of valve opening to throttle the air entering the cylinder. In such engines, there is less pumping loss, hence improving fuel economy, which was the holy grail of diesel engines in the first place.

It is the Valvetronic on BMW and Valvematic on Toyota.

This decreases performance but just makes a noise. It doesn't filter to the required standard and has a much smaller surface area than a paper element. The car is *FASTER* with original filter and box - you were well and truly conned like most boy racers.

"Tell them it's to make a car fast and they will pay anything", that's why people waste hundreds on crappy tuning boxes which cause engine problems. They are ashamed to say they were conned.

@urbex2007 Agreed, a note to the owner of the car and video, did you know that courtenay sport and thorney motorsport (vauxhalls top tuners in the UK no less) use the air box off the 1.9 cdti on there 330 bhp power kits? So they must be good

It's comes back to the old saying "if it ain't broke, don't fix it"

Might I suggest putting the old box back on with a paper filter in it and just change the front pipe (all those extra bends in the simota kit can't help performance can it?)

[bhendriks15]

@urbex2007 What about keeping the orginal airbox but replace the paper with a Simota ?? whats your opinion ??

[ulef19]

@bhendriks15 Your thought is right, plus the airbox has very long pipes, the air is doing a huge course till it ends into the manifold.

[jarrus464]

@bhendriks15 don't bother, there are far more restrictions in your intake than the filter, sort those out first, it will be cheaper

[urbex2007]

It will not increase power in any way whatsoever. A paper element is better as it FILTERS the air. You want a sandblasted turbo?

[carozomagno]

what you gained in horsepower ???

[kal12345]

3 or 4hp ;)

[16airassault]

Can any1 please tell me where you buy this from simota website doesn't have it any help please

[simsek1702]

10 beygir artış naaaaahhhhhhh 10 beygir bir defa hawa filtresi her zmn arabayı öldürü yazıok yaa motora

[MCMazzo]

`katiliyorum

[stevenrigbymiller]

sounds good

[simonali6819]

Up to 10BHP shown on the rolling road, apparently.

[R3ganBiH]

and the performance with "simota air filtr".. better or??
