19,xxx miles . Its a short ram air intake kit (cone)
Sorry I meant that After the 1st CEL light came on i've been driving like a grandma.
New subaru oem plugs are $16 a piece. i called south shore motors for a price. I asked it it would be covered under warentee and he said he didn't know. he also said they would not look at it with out the CEL on. i asked if should drive carefully, avoid WOT or rpms over 4K and he said no. drive 100% normal on it until the CEL comes on again ...

(i don't fully trust them for service as they did a poor job servicing a 1996 impreza brighton L about 6 years ago . ie did not put the oil cap back on, steering fluid cap, and failed to reconnect the Fans)
i may call micheal hohl to see if they can tell me clearly if it will be covered. i fear south shore motors. [the 96 impreza, and i got Tboned there picking up an oil filter 5 months back]
