Hey All!

If you doubt the value of cold air you no doubt don't run an intercooler.

The simplest cold air box is the OEM one together with its snorkel and a high flow panel filter but if you want a shield for your pod(s) they are easy to make. Do a search in the Skyline section - there are a couple of good articles on how to do it for very little cost.

A while back SK did the testing with two temp sensors demonstrating the hugh difference between ambient and underbonnet temps.

I haven't read any articles saying heat shields are for "wank factor". Most people understand the need - not everyone gets around to making one.

I have made a couple of homemade cold air boxes with 0.6mm sheet aluminium and foil lined foam (clark rubber). A little bit fiddly but do-able with some patience.

I just posted about a heating problem I have. I could not get the stock air box back in after mods as the BOV is in the way. I have the cold air induction plate still fitted Maybe my first move should be to move the BOV and put the.stock box with Redline oiled filter in, although some say the oil can upset the AFM. It will be a PITA but worth doing.

My coldbox

I made the cold box out of carbon sheet with gold reflective finish engine side . It is fed through the vent in the nismo front through fibreglass ducting.

It was pretty simple to make but took quite a while to get the top contours of the box exactly right so it seals to the bonnett "carpet" as the bonnett closes using stagea door seals.

I have not noticed any sudden power increase but the area is definately cooler than the engine bay so it must be doing something worthwhile.

If you look around you can buy a Pipercross filter (not oiled) PX-PP1128. Also fits rally evos and falcon!
