Air Filter & Intake Discussion
- Thread starter Crocoman
- Start date
Finally got my airpipe and turbo intake in the mail...but I think there is a problem.
The flanges on the airpipe aren't bored out! See pictures
I know other people on this site have purchased the airpipe thru Gruppenzwang. Was your airpipe the same? Do I have a problem?
My neighbor owns a metalworking business so If I have to bore out the elbow myself no big deal. I can't believe it wouldn't come to me finished...WTF!

If I recall others have shown the same. It's not going to disturb the air flow thru the pipe or cause any problems. 
Oh shoot, I didn't see they didn't bore thru the main body. Now I understand what you're referring too.
That's not going to work at all. You can bore them yourself but frankly I'd send it back. Sending them a photo and asking for a replacement to be sent first and an RMA postage paid, with the one to be returned.
They didn't QC the pipe at all.

Follow up...Mr. Venner from Gruppenzwang called me. (He has a spy in the forum)
Anyway, a new (completed) airpipe is being sent to me tomorrow.
Although my experience with them was a nightmare, the guy does exceptional work. Materials for the pipe and hoses are as good as can be found and his welds are beautiful. As soon as install the parts I'll upload a pic. I expect I'll be pleased in the end. I just want this to be over.
This is a good thing!! At least he's acknowledging the issue up front and is taking a positive step to correct it.

Dude, you said it. The guy is really nice and does great work. Yeah, their customer service sucks ass but at least he's trying. If I stuck to principal I would never purchase from them again but I really can't say that because I'm not a professional race car driver and don't need the parts tonight. As an independent parts provider he does some of the best work I've ever seen - you just have to wait forever for your stuff. I can wait, they're figuring it out - I respect that. I'm just disappointed with my experience, it happens.
I would do business with them again. But I would make sure I have a delivery and pay by date first.
Well, it's pretty cool that he contacted you before waiting for you to get in touch with him
Sorry if I’ve missed it but I’m contemplating the pipercross intake for my I30n. Does it require a tune after?
Nope.
No filter or any induction mods required any further tuning.
Obviously a proper remap can take into consideration that the intake has been changed but all intakes are "plug and play"
Hiya guys i ordered a pipercross filter and fitted it, i dont seem 2 be getting the louder turbo flutter when driving i can hear filter sound dragging the air in and car sounds slightly different but doesnt seem to be getting the flutter after i have fitted it and refitted to see if fit ment was out and not getting suction etc but is it me etc sorry to sound stupied guys the fitment etc r crap haha anybody help me probs laugh at me but help me
You won't get flutter with just an airfilter? You'll need an open induction kit for that.
You can run with the airbox lid of for an extra sneezy sound if that floats your boat. (I wouldn't though as the lid helps locate the filter. Pipercross isn't an amazing fit to start with).
Okay mate thank you very much sorry sound stupied, yeah the fitment r terrible ill admit
What you're hearing isn't turbo flutter anyway. It's simply the operation of the diverter. Turbo flutter is something entirely different.
Finally got around to installing the turbo intake and airpipe. Sound is better, throttle response is better - only slight differences but noticeable nonetheless. I'm happy, and in compliance with TÜV, so the Germans are happy too. I also have a Pipercross (dry) filter.
If anyone is thinking of replacing their turbo inlet adapter to a larger one...have a shop do it if you're unsure about replacing motor parts. I know what I am doing and had a heck of a time. It's such a tight space!
