How to retro-fit the GTE air intake to a Mk7 Golf

Sort of, still question why anyone would add the blanking plate to cut off air flow that is designed to cool the engine bay. See this sort of thing in the GTI mod posts as well. I don’t think any ram air increase would offset the increase in under hood temps.

Because the engine bay is getting plenty of cooling through the grill and radiator. This small duct can't possibly be integral to engine cooling. My hypothesis is that it's just to keep the intake from getting blocked up (snow) so that it can pass through and still allow airflow to the intake.

please go read the first few posts... I explained this...

Hi VWolks, just small remark. I’m also considering this or equivalent upgrade to provide more fresh air for the engine (mine is CZDA, same HW like Dave’s but a bit factory tuned SW). However, I remember from modifying older VW naturally aspirated petrol engines that changes of the intake length is having some effect on agility. A shorter one (prior to the throttle unit + MAP sensor) made the engine more agile in low revs but weigh on high revs performance. Does anybody noticed comparable change of feeling with this modification?

Coz opening the right side makes it shorter regardless installation of the water baffle and closing the left side. It leads me to possible solution to forget about the left side (let it blow/snow and to perhaps a bit cool the engine) and (almost) fully open the right side. The airbox on 1.4TSI is a tad higher above the air entrance meaning that the spray would need to come under the bonnet, turn left avoiding to exit thru the drain „penis“, than about a feet or more still to left than another 90deg turn upside…pretty complicated journey but I do not want to underestimated the dynamic of fluids.

shorty_cz, you are correct regarding the shorter and longer intake lengths and their effects on the rev performance. But this does only apply for naturally aspired engines. For turbo charged engines it is just a question of high and untroubled air flow. The performance in low and high rev ranges is mostly defined by size and geometry of the turbine and compressor wheels in the turbo charger.

Thanks for your remarks. I will think about that - contacted the dealer and costs of the tune is relatively high (equals roughly to gasoline for a month) for two small pieces of plastic.

The intake on the Golf 7 1.4TSI is already a cold air intake. It's just, as you said, not so nicely designed imho. That is why I am also trying to rebuild it in a way that I imagine is better. I detailed this a little more in another thread.

Yep, I saw the thread but since I still have factory warranty for another two years, I will refrain from visible tunes like putting large red hose in the middle of engine bay or to switch airboxes (although for another genuine version).

A bit OT but I did comparable swap in the past with Mk4 where airboxes of some petrol engines were integrated in large engine cover and got freaking hot. Moreover, bimetal controlled flaps to quit temporary heating from exhaust manifold broke up again and again (strange, on my Mk1 is still working perfectly). However, it was perfect place to re-heat take away pizza during trips.
Agility considerably improved when installed GTI/TDI box that sits closer to the headlights (basically the same area like EA888).

I liked the eye catcher effect of the red hose :D
But for the further changes I will switch to all black probably.

Yea, well, I guess the engineers didn't wanted to let the people eat cold Pizza. ^^
Although nice to hear, that moving the air box did have a effect. I am always a little bit confused by some decision, that are made by the manufactures. I guess in the end it is most times a cost factor.
At least they already improved the airflow from Golf 6 to Golf 7 alot, by switching the intake side of the turbo and shorten the way for the air from the airbox to turbo. (for the EA888)
