Who belives in the IPD plenum

[bcrdukes]

I initially had my fences up on the IPD plenum etc. but curiosity got the best of me so I dove in head first. Suffice to say, the mods put a smile on my face every time so I have no regrets. I can certainly respect everyone's opinion on where they stand on this topic, but if you have the opportunity to try it out, I would highly encourage it. Don't knock it until you've tried it. Enjoy your cars in good health!

This has been a very discussed topic on the forum. Pros and cons, price. I think in the end for best results it needs to be used with an exhaust upgrade to see most benefit. This is based off following many threads of discussion no experience.

I did notice that the pull is more linear to red line but that could also be because I switched over the the FVD Brombacher "Sound" exhaust. I also have the FVD Brombacher long headers and BMC filter pending install. For the time being, I don't have a software tune, but ultimately did notice a difference. I'm happy with the upgrade.

Just an update: I installed the BMC air filter today and flashed my DME/ECU with the FVD Brombacher tune. There is a significant difference in throttle response and the engine pulls all the way to redline much faster and much more linear. Dare I say it, and there will be nay-sayers, but the car is scary fast after 3000rpm all the way to redline. It's going to take a bit of adjustment and seat time for me to get used to it. I'll go as far as to say that with the tune, this car can keep up with the big boys on the highway.

I'll be installing the FVD long headers later this summer and then re-flash the software. For what it's worth, I like the FVD tune because when you add the different bolt ons to your car as part of staged builds, they allow you to update the tune for free.

My two cents: The IPD plenum alone might not be worth it, and gains will be marginal at best, but when you add in the intake, header, exhaust, and especially a software tune, you are golden. But please do not expect the performance of a twin turbo setup. That's not realistic. Go buy a car designed to go fast.

Any change in sound with the BMC filter? I've been meaning to change my filter and debating between oem paper and BMC. I don't really care if it adds a few hp, I'm just interested in more intake noise! Would it be worth it from that perspective?

Already done de-snork btw

Haha to be honest I'm not sure yet. I drove along the 400 series highways last night with the top down.
