Thankfully my mk7 came with a racingline intake system and a racingline exhaust. Would you say a lpfp would be worth getting as well? If so what are the better brands in IC and DP? I've seen a lot of APR, CTS, MAP, IE..
Spark plugs and an inlet pipe would be a smart idea since I'm upgrading from stock turbo correct?
I don't think a lpfp would be necessary unless you get a hybrid turbo (I'm sure someone will correct me if I'm wrong...)
Pretty much any intercooler will be sufficient, so you can spend $300 for a twin-cooler (fmic with pipes that also utilizes the stock ic) or $900 for an OEM location cooler for pretty much the same results.
If you really want the "best" then take a look at Baun Performance but note there will probably be a waitlist of a few weeks or months and the price isn't pretty. My CTS downpipe was $500 and gets the job done but doing it over again I'd probably go with 034 (cast, stock location cat, flexpipe). The ARM unit looks like a great bargain
Yes add an inlet pipe to the list. Spark plugs are subject to debate on this forum, many people prefer stock range Ruthenium plugs despite every tuner I've seen recommends 1 step colder such as the NGK RS7 plugs. They're cheap enough you can try running both to see if there's one you prefer over the other
