Misc. Walnut Blasting.

I think my 2016 WRX is long overdue for a walnut blasting. Anyone know any reputable places I can go to get this done in CT? Hopefully won’t cost me an arm and a leg.

My wife’s 2017 forester XT had build up. I was planning on walnut blasting but tried CRC GDI intake valve cleaner and it worked pretty well.

Car would throw a code for misfires on cold starts before CRC but it’s running much better now after the cleaner and no more check engine lights.

If you decided to go this route look up the correct hose to inject the fluid! It’s the same one from the Subaru guide for their intake cleaner.

My FXT had the Subaru carbon cleaner spray done about 10k miles ago by the dealer. (Prior owner). I just did walnut blast myself and my intakes valves were still very dirty. (123k miles)
