Euro
Pros:
- PnP system installation - re-uses factory upper snorkel
- Filter access is top loading - simply remove a couple screws, take off top, replace filter, replace top - no need to remove entire airbox & disassemble as with PI.
- Uses round style filter with greater filter surface area vs PI flat style
- No additional secondary carbon filter in airbox as with PI
- Warranty is not voided as it is an OEM BMW part
- Carbon Fiber lid cover available aftermarket from Carbon8 if you want the CF look
- Increased intake sound (if you're in to that)
- Feel slightly better throttle response (although no dyno results to prove)
- Cheaper @ $400 than PI @ $700+ (I only paid $75 shipping charges for mine as I did an even swap for my factory airbox with a member in Singapore who needed the back half for his PI install)
Cons:
PI
Pros:
- PnP system installation
- It has slightly larger inlet size where connects to upper snorkel with corresponding larger outlet upper snorkel
- Has secondary air inlet from rear of box to windshield cowl area (don't know how effective this is as it is relatively small)
- Warranty is not voided as it is OEM BMW part
- Increased intake sound (if you're in to that)
- Carbon Fiber lid + upper snorkel
Cons:
- Re-uses factory airbox back half - so secondary carbon filter will still be intact & would have to be Dremeled out if you want it gone
- Since it only replaces front half of your factory airbox (you retain the factory rear half) - to change filter you would need to completely remove the airbox as before
- Uses factory flat style filter with less filter surface area than Euro round style
- More $$ than Euro
For me, the deal breakers on buying the Euro over PI was the ease of filter change, increased filtration area, & of course the cost of the Euro vs the PI... |
Damn .. Well I pretty much think you just sold me on the euro box
thanks !
