To be honest, it depends entirely on the car and state of tune. On Subarus I know a lot of people recommend sticking with the standard setup until you start reaching big power, when the advantages of being able to get more air in quicker start to show. Or you fit an FMIC, and then you can't use the stock setup..

Induction Kits. Do they actually do much at all?

Minz addded 20bhps!11.
the standard airbox on an mr2 turbo is quite restrictive, i swapped mine for an ARC induction box, didnt fancy a cone filter sucking in hot air from the engine bay...
couldnt tell you the gains it gave as i upped the boost & fitted a different exhaust between dyno runs

I wouldnt spend more then 50 but its worth doing especially when the normal filter has to be replaced sometime anyway. It'll increase torque more then bhp and of course induction noise.
I spend buttons on my car and I'd still say it was worth it, combined with exhaust mods and you should notice a difference in feel and power even on a fairly modest engine

It's probably got a thermostat somewhere that will shut warm air off to the manifold once the engine is warm enough. The Stag has a warm air feed from above the exhaust manifold to help with cold starting, but that closes off and uses a built in cold air feed from above the rad once it's warmed up.

Probably better though
Lots of induction roar! Could do with some more cold air though
Lol too right. My GT6C has pancakes on it and it's great, with a lovely induction roar while the car is moving, but slow traffic and tubular manifolds directly beneath the carbs soon means that under bonnet temps rise to a level where the car stuggles to keep running.
It needs very gentle fettling in traffic to keep it going, especially on hot days. Once you're out of the traffic it cools down quickly enough, but I very much doubt that the pancakes add any HP at all due to the general warmth of the engine bay. If I was keeping it I'd add a GT6 (or sprint) air box and some pipes to a cone filter mounted somewhere in the nose. That may make a difference.
Depends on the car, some turbo cars are really asthmatic so a decent air filter and exhaust can really help, some cars already have excellent induction as standard so there's no real gains to be had.
My R5 GTT lost power with a Pipercross (but it sounded cool), my MR2 really benefitted from the Apexi and the Elise feels much sharper with the ITG (actually, thinking about it the Pipercross was about £50 and the Apexi/ITG were £200-£400 so maybe there's something in that?)

Sounds like a highly complex and technologically advanced cold start system there I've got a ITG Maxogen on mine and it seems to do the job nicely but it could be a placebo effect for all I know as I changed the manifold, decatted and put my exhaust on at the same time. The website however claimed to have RR proof of 8bhp difference on a stock car. Who knows? It looks pretty and can't do any harm

I'm curious about Induction kit on the Celica VVti myself. I read somewhere some bloke reporting good results but little other confirmation that it's worth it.
Any Celica owners using it?

How much did that set you back?

i did a before and after on my XR2..
stock, stock with K&N, stock with K&N and ashley 4-1 rally system.
was more urgent... and increased topend a bit too... had 145 on the clocks at the end of it.

My K&N makes a noticable difference in throttle response, most likely because I took about 12 miles of pipework off the original intake system. As for power increase, maybe, had it RR'd at 164bhp, but whether it was making 163 beforehand, who knows.
Got a K&N on atm, but a guy at work brought me an Apexi jobbie back from Japan (dry filter) so i'm going to give that a go. Going to get a cold air feed made up, thought about moving the kit behind bumper with some mesh, but it would get so filthy it's not worth it so i'm just using some piping to feed from where my front fogs currently are.
Tbh i've never driven my car with a standard airbox so I can't comment on differences. A lot depeneds on how restrictive the stock airbox is, and where it feeds from.
