Jamie,

Not just Mines mate, the majority of Japans tuning world (Skyline) steer well clear of cone filters. Take a look at the GTR magazine or the Hyper Revs magazine, nobody uses cones. Also, London air is much more dirtier than Japanese.

My filters are absolutely filthy, I'm spending a lot of money on my car, but none for performance gains now, all for safety.

Thanks Cem.

This is an interesting area and I don't doubt your right.

It will be interesting to see what the UK does moving forward.

So, tell me is it for your car??

The panel filter? Sure it's for me.

I just want to buy the housing, then I'll buy a high performance panel filter.

Im just worried because I've seen how much oil and dirt actually gets through these cone filters.

Cem,

I know this debate has moved to another thread but I've just had a look through Hyper Revs vol. 57 and I could only find 1 stock airbox shown. All the rest were cones and the like....

Hyper Revs

Snap Pete. Have just been through no.58 and is the same with this one. Only a couple of standard airboxes.

About filters

Hi there,

It is very interesting discussion.
Please do not forget that your cars are usually not racing car, or demonstration car of the tuning garage.
You cannot maintain your engine as often as tuning garages usually do.
Of course, it is up to you which type you choose, but once you blow your engine, it costs very expensive.
The panel type filter is applicable up to around 600ps, so if you'd like to go for more than 600ps, you have to use foam filters to get enough air.
Further, especially in the case of GTR34, the air is not go through the engine well because of the front diffusers, so even when you drive fast, the air will get hot with the engine temperature and stay in the engine room. Then foam filters will get hot air from the engine room.
You can see the intake temperature on the MFD.

Yours,
Shin

Mine's Awesome Car

Hello Shin.

I noticed on your lovely Mines Car you still had the standard air box but it looked modified.

Can you tell us what was done to it and why please?

Cheers

Modification!?

Hi Paul,

What do you mean "it looked modified"?
If it is about the bottom of the air guide, it has modified to be able to fit stainless steel intake pipe.

Yours,
Shin

Air Temp

Speaking with Guy the other day about this Shin so hope you can clarify this.

Surely the main point is regarding the temperature that the air exits the intercooler. Irrespective of what temp it may be going in, surely when it comes out of the turbo/turbos heading for the intercooler it reaches a certain temperature anyway due to the heat from the turbos.

Added to the air box theory I did notice that the Top Secret 34 had a custom made airbox fitted, with filter inside. Is this to draw on 'stiller' air or 'colder' air or both? Pic below.

My opinion

Hi Glen,

I think you understand the merit and demerit of the foam type filter.
Even intercooler will cool the air, but it is better to get cool air at first.
I think it is "both".

Yours,
Shin

Turbo Temps

Hi Shin

So then if we knew the heat generated by turbos in all ranges then we would be able to quantify whether it's worth worrying about filters/boxes etc.,

Because if the intake temp is lower before it reaches the turbo/s it don't matter as the turbo/s heat will take it up anyway.

I reckon that the heat developed by the turbo/s is more than the ambient going in, so therefore the best way to cool the air is with the I/C. Then we go to OTHER :eek: types of cooling.

I have to stick to Guys reasoning here. I seriously doubt that hot air is sucked in by HKS type filters(or other non panel items) when driving at higher speeds. I certainly noticed no difference from a standard filter to the HKS ones by keeping a close eye on the intake temp read out on the MFD. Sure the air get hotter while sitting in traffic but it used to be the same deal with the standard panel filter. Furthermore, as Glen said, we should be more worried on the actual temperature on the other side of the I/C!
I still believe the real argument for replacement filters lies in the quality of filtration...
Furthermore Scott, our resident air filter specialist, seems to think that high performance panel filters are not very good at filtering. Kind of depends on the trade offs you are prepared to live with.

So

Hi there,

So, I posted "It is up to you." before.
I've told my and Mine's recommendation with our experiences.
Again, it is up to you which type of filters you use.
You cannot force someone to use particular filters, and so do I.
I posted just my recommendation.

Yours,
Shin
