CPE intake design issues

[SilversunMSP]

I bought a CPE intake for the Speed6 and I love the gains but there one shortcoming. The thing gets saturated everytime in rains and causes a CEL. I noticed the location of the MAF sensor is alot closer to filter than other intakes like the mazdaspeed. Is this my problem? The filter is soaked after a light drive in the wet.

Anyone? It just seems like the MAF is too close to the filter. The Mazdaspeed and AEM intakes place the MAF a bit further up.

The AEM/MS CAI also gets wet in crappy weather, and can cause a CEL for MAF voltage too high, so it's not their design. It's more so the problem that the drivers side inner fender is slatted, and water can come through there.

get yourself a injen hydroshield for piece of mind....and no more cels. only like $15.

tunersteve, i wonder if one was to block the inner fender slats if would help this issue any or hinder and cause other issues. thoughts?

I live in Arkansas and it rains like hell here. I had the CP-e with the same issue and I could not stand being scared to go through puddles. I bought a Cobb SF and I have no worries now.

I did it with a piece of aluminum and had good results, but my IATs went up about 20 deg. across the temp. range as a result. Yes, it works, but there are tradeoffs.

I did it with duct tape when it rained hard here a couple years ago, but you could really FEEL the difference too. Now I just run the Injen Hydroshield and have no issues during a hard rain.

I had issues with slush, and even with the Hydroshield, it got wet and threw a CEL. I cleared it with the DH, and things were fine. Problem is, any voltage over 1V on the MAF triggers that CEL, so a drop of water will do it if it hits the element.

Duct tape, aluminum flashing, or something similar will do the job. I'm actually considering running an SRI in the winter just for ease of swap and to avoid any issues.

Covering the vents in the wheel well defeats the whole purpose of a CAI. I'm glad to hear the issue IS NOT just related to the CPE intake because I have the utmost faith in them and their products. I think I'll get a hydroshield and take it easy when it rains.

It's not a huge issue to cover them, but you will see your intake temps rise a bit. I never had any adverse effects from that flashing covering that area.

You could do a two layer setup of fine screen on the inside of the fender liner to slow the water down from hitting the filter.
