HKS Air filter problem?


Induction

Recommended Posts

Hi all

 

I've fitted an HKS air filter, the Super Power Flow, and was wondering what happens to the connector that went into the old airbox.

 

The engine starts and runs fine but the engine light is permanently on and the Overdrive light blinks. Before I run the car I want to be sure what is actually going on.

 

I think I read somewhere on the board about re-setting these lights, but why did they come on in the first place?

 

Anybody got any info on this?

 

Thanks.

do you mean electrical connector or pipe connector?

That bloody thing still has to go in-line doesn't it?!!?

 

I feel like blaming the instructions (only written in Japanese!) but at the end of the day I think I've got to accept that I should have realised the sensor had to remain in-line!

 

At what point along the piping should the sensor be placed, and does it need any modification to allow fitting?

Looks like the instructions and kit you have are for the Jap spec, which doesn't have an AFM.

 

Not sure how you are going to hook that up on a UK spec car, but you defenitely need to keep the AFM, well for the time being anyway ;)

Whoa there!! The kit is for Jap market cars, you cannot use it on UK-Spec, there may be a different kit to satisfy the US market that uses the same air flow measurement. It's a wonder the car runs usably at all with no AFM fitted. Return it to stock immediately, you could do a lot of damage.

 

My opinion of the HKS filter is well known, and not favourable. That does NOT mean that I think all HKS stuff is bad, some is excellent (mainly the stuff made in the Uk and sold under licence :-))

Right, before anything was done in terms of actually running the car, I contacted my supplier and checked a few things.

 

Turns out that I needed to shorten the main hose (black one) so that the AFM could go back in-line and still allow the filter head to be in position.

 

I had to get two pieces of piping to go either side of the AFM and they're secured with juby clips.

 

The car runs really well with it on and the induction noise is great to hear. I think general pickup of the car is better now as well.

 

Chris, I'm a bit concerned about your comments on how the induction kit is only for Jap spec cars. My supplier knows the full details of my car and assured me that they had got the correct kit. I'll check into this for peace of mind.

I have been told that there are 2 induction kits available, one for UK and one for j-spec and that you should not need to hack any of the pipework or hoses about to make it fit. Sounds like your supplier has given you the j-spec one and they must supply you with the UK spec otherwise you will spend you life trying to get it to fit right.

That's how i have been told it is too, by HKS. Cheers JB.

Here's how I ended up installing the induction kit.

 

After I was done I got it checked by APB and they told me they were more than happy with how I had gone about the installation.

 

The car seems to be running fine with it in place.

 

It's difficult to see from this shot but there's about 2 inches between the front of the filter and the neearest obstruction.
