Default Blocking your intake resonator?

I've personally never really seen a reason to block it, but I know a lot of guys do it. If you do and you use one of those expansion/test plugs that has a cairrage bolt with a wing nut or something similar, make sure the nut stays tight. Also, it would probably be a good idea to use one that has metal ends instead of plastic. I just saw this a couple of days ago.

The plug I found had a metal washer that was too big for the resonator to fit back on the truck. I ground the washer down but it still will not fit down the hole. And it is a tight fit.

As for the bolt, It is drilled and has a safety pin in it so it cannot drop into the intake.

Also when I blocked the PCV, did the same thing, drilled and installed safety pin.

That's a good idea on the safety pin. I'm not sure if anyone else sells them, but Alligator sells a billet plug with an O-ring seal for both the resonator and PCV.

Why not use a 2" rubber cap? No way for anything to fall in and it fits perfect.

I removed mine for access, I don't think there is any performance gain at all.

X2 on the rubber cap. Worked great for me also. Did a few friends that way to. No issues. Took mine off now cause of the mpi twins I'm installing this week. but would use the cap again for sure.

Untill they crack and let your sweet engine eat dirt. Ive heard of too many cracking along the seam and alowing unfiltered air into the intake.

What is wrong with a $3 rubber cap and hose clamp? sticking something in the hole is asking for it.

I have never seen one crack. Not saying it can't happen, but I can't believe it's all that common.

Think its more of a first generation engine issue, plus there might be something in the air here...LOL! There are 2 i know of here locally in my dinky town, and a few ive read about online. I think its prety cheap insurance, provided you do it right.
