The car feels sluggish at 0.04'' as they came. I am looking to close the gap towards 0.032''. I wouldn't try it mysef, since I don't have the tools for it. Any suggestions on a shop in the area?

what makes you think it's the spark plugs that are making the car feel sluggish? Maybe it's a boost leak or bad gas...

... before I switchwd the old (27K miles) stock plugs with the new IK20's. I noticed the difference/lag right away. Check out the link above... It can't hurt to try to regap. I am certainly not going to return them back.
