Hi to those of you who know more than me I apologise which is probably everyone.

I want to upgrade to 550cc injectors I have seen a set on ebay

Can these just be exchanged or do I need to change fuel rail???

Oh and do these look a good buy??

 

Providing that yours is a wrx sti 02 onwards i assume that they will be a correct fit and wont need the fuel rails adapting mate, but i will stand corrected if i am wrong, as for price mate they dont seem a bad price as they are brand new but there often a few sets of 550cc injectors appear in the for sale section so you may be able to save a few quid if you were to opt for secound hand although if you want it to be right then new is the best way normally, although i think denso is a relatively cheap basic make too bud totally up to you at the end of the day.

 

I went for a set of STi pinks often available for a similar price second hand and you know what you're getting.

 

its a 2002 wrx

just seen these are they a direct fit no need to change rails etc..
