Just a clarification to SVTCole's post about allowable mods for Stock class competition, the replacement air filter must fit in the STOCK airbox. The best choice for this tends to be a K&N air filter. The only reason I mention this is that we had a person show up at a local event with a K&N cone filter attached to the MAF thinking it was allowable due to the air filter replacement rule.
