filter=detonation

i was reading one of my import mags and i read that with the heats the engine makes and having a open filter by the engine, that this helps to detonate thwe engine? So my question would be is it better to run a drop in k&n filter or an open element filter? or do i really need to worry?

They’re probably talking about an SRI. If you run a K&N drop in, you’re essentially running a stock intake and should be OK. Ideally, either get a CAI or have one made, then you completely eliminate the problem you’re worried about. :slight_smile:

This is because the open element filter is sucking in air from within the engine bay, which is ussually warmer. And the stock air box ussually sucks air from the front of the car or the fender. But I don’t think it’s usually to much of a difference. SO in a way…yes it increases the risk of detonation. But maybe only by a few percent, which isn’t enough to worry about unless you are allready pushing the threshold of detonation. On most turbo cars, your intake charge is ussually allready very hot, but on NA cars a few degrees of air temp can make a bit of a difference in milleage and power down low in the RPM’s.

Assuming you drive a NA car, I would say that the advantage of adding a short ram intake system or just a open filter isn’t worth it. I say this after putting a short ram AEM intake on my Integra GSR. However a cold air intake or aftermarket intake box could be a good investment along with headers and exhuast if your looking for more top end power. But you will probably loose low end torque.

Hope that helps

I really wouldnt worry about it. Once the car gets moving the temp under the hood will drop to a reasonable amount. Dont you notice how many things on a stock vehicle heat up the intake piping.

very true, just did’nt notice, and yes my car is NA and this summer i do plan on getting some headers exhaust and hopefully a cai, headers probably hotshot, cai probably hotshot as well, and exhaust i am thinking a custom with resonater and a borla muffler with a tip, just need to know a good shop

stop reading them funny magazines. most of the editors/writers never even took a motor apart or had a chance to read a mechical enggenering books. :partyman: If u have NA chances of detonation are 1 in a million , u may get a ping if it gets real hot or u advance ur timing like a homo. that s about it. Factory ecu usses feedback from coolant temp sensor and few other things to reduce timing when it gets hot anyway.

Detonation is more of an issue on turbo cars, and again if u tune ur car right have proper fuel and timing curves set u’ll never have deto …ecu on turbo cars still has a scale to drop timing etc based on outside temps and i doubt u will ever run 30psi + where amient temps will be sufficient to cause deto…well if u do u be running an ice box or alcohol plenum injection at that point anyway.

You have the same cone setup as me right? (MAF adapter, and cone filter right?) Yeah, you’d have to be running something like 60 Ocatane to even get a det to happen, dont worry about it…

The bay does get hot, but not that hot, you’d be surprised how hot it has to be…

yea the exact same setup, aiigth cool, thanks alot guys
