Since the day I have bought this car it has had a small hesitiation especially when mashing the gas. It just falls on its face unless I have it in a certain RPM range. Its a hesitation that seems like a lot of B5 A4's have from the research I have done. The solution would seem to be to buy either the 4 prong Hitachi bolt downs and eliminate my ICM or buy the newer 2.0t push ins with adapters.

I looked over on 034 motorsports and it seems like both of these options are covered. The newer 2.0T push ins seem like the way to go with them being cheaper and being able to run better spark gap. However no where is it stated on how much HP they can handle and the bolt down Hitachi are advertised past 400hp. This is a concern of mine as I later plan on making 350awhp. However it seems like the Hitachi also have the same problem as the older 3 prongs I have in my AEB powered A4.

My question is if the push ins will be able to handle 350awhp?
How dependable are the Hitachi bolt downs?
Do they both use the same connector?
What is a good sparkplug to use with the AWE K04 kit with Giac pc16 upgrade?

I apologize if I sound like a noob with asking questions like this but its because I am a NOOB when it comes to the Audi A4 and the AEB engine.

Thanks

 

I can't say from personal experience that 2.0T coil packs will handle your goals, but I've read of guys using them for higher HP. People have even used the AEB coils for 300+hp, and as you know they're quite weak compared to 2.0T coils.

For a while I ran bolt down coil packs with the ICM delete (same ones you're talking about). I found a gap of 0.028" was still necessary after a little trial-and-error. With 2.0TSI coil packs (part # 06H905115A) my gap is about 0.040" ! They're smoother than the bolt-down coil packs, and yes, they use the same connector.

Your setup would work well with NGK BKR7E plugs (I've been using them for almost 2.5 years). These are one heat range colder than stock, and a copper plug so they cool off a bit faster than platinum or iridium or whatever. The downside is that replacement should be every 5-8k miles, but at $2/each and how little time it takes to swap them, it's really not a big deal.

Were you planning to buy an ICM delete kit (from 034 or IE) or were you planning to buy the harness and wiring it in yourself? I did the latter and am glad I did... you can really get rid of a lot of wiring and make it look cleaner (not to mention save lots of $$$).

 

Looks like its about $400 for coils, wiring harnesses, coil bracket adaptors and shipping at 034. I might be doing this eventually. Edit: for the 2.0tsi coil setup that is.

 

I bought the coils and the harness from ecs and I'm going to splice and solder it in. I have some top notch 3M shrink tubing. Not only will it be cleaner install but also a connections are fail points and weaken signals.

No way I'm going to pay $ 80 for the adapters from rai. I'm going to cnc them myself. Copper is actually a better conductor old electricity. Platinum and iridium just withstand abuse better.
