I've noticed that in damp conditions my car seems to hesitate, but only when opened out and with fairly high rpms. As the coil packs are not exposed, I could only put this down to the mushroom filter being rubbish and allowing moisture to hit the AFM wire. Has anyone else had this problem and would an Apexi sort it out?

 

Cheers

When you say mushroom filter do you mean the HKS foam one. Notoriously bad in the wet. The Apexi will improve it, but the best improvement is to fit a splash guard under the filter.

I'll try & knock something up, if that fails then I'll swap the HKS for an Apexi. Glad it's a common problem and not something else!

 

Thanks for the tips.

Yes sounds like water getting on the AFM.

I wouldn't recommend you change to an Apexi without fitting a splash guard first.

That's what I did and the Apexi's soak up water like a sponge until the car won't run or even start the next day.

I've had my Apexi's in the oven for 3 hours and they are still so wet the car won't start!

Cheers for all the info guys. I want to make something lightweight and without restricting the airflow if that's possible!!
