It is Miller's position that Stewart-Haas Racing manufactured the spoiler themselves rather than obtaining it from a licensed vendor and that the part was made in manner that violated the rules.
Miller said that series officials did look into if the infraction was an L2 penalty, which would have been a 75-point penalty, six-race suspension and fine of between $100,000 and $200,000 but determined that the infraction was an L1 penalty.
Greg Zipadelli, vice president of competition at Stewart-Haas Racing, said the team will not appeal the penalties. Harvick gained the maximum 60 points at Texas because he won both stages (10 points each) and the race (worth 40 points).
"We have small windows and tight windows to get the inspections done, and we might spend in the neighborhood of five minutes with each of the 40 cars for the three-hour window that we have for inspection", Miller said.
Harvick still has the possibility to clinch the final playoff spot available on points. Texas race victor Kevin Harvick lost his automatic championship berth from the victory because the spoiler on his Ford was out of compliance.More news: ‘Meat tax’ could save thousands of lives, claim researchers
Tony Gibson will serve as the interim crew chief on the No. 4 over the next two weekends.
"As everybody knows, we issued a penalty for the 4 vehicle today, and the penalty notice, which I'm sure you all got, it was spelled out that the splitter or the spoiler did not meet the CAD file", he said.
"We work tirelessly across every inch of our race cars to create speed, " Zipadelli said. "Instead, we will direct our immediate focus to this weekend's event in Phoenix and control our destiny on the racetrack". The infraction was discovered during the usual post-race tear down at NASCAR's Research & Development Center. Harvick's win at Texas no longer automatically qualifies the team for the Championship 4 in Miami. Now, three spots in the finale will be up for grabs Sunday in Phoenix.

Miller said NASCAR officials at ISM Raceway in Phoenix this weekend will further scrutinize all spoilers before cars go on track as a response to the penalty. Cars will not be taken to the R&D Center after that race.
As a result, Harvick's victory does not count toward automatic advancement into the Championship Race at Homestead.
"We've heard the fans kind of call out for, 'Why don't you disqualify the offending car?' and that's actually a topic of discussion along with many other things related to the deterrence model", NASCAR Senior Vice President Scott Miller said Wednesday.
Blaney's crew chief Jeremy Bullins and Jones' crew chief Chris Gayle have also been fined $50,000 each. "We will now return our focus to Phoenix, and the battle for a championship". Jones crew chief Chris Gayle was fined $50,000 and auto chief Jason Overstreet was suspended the next two races. Driver Ryan Blaney loses 20 driver points, and the team loses 20 owner points.
It took until Wednesday for the penalties to be announced because the cars were in transit Monday from Texas to North Carolina.More news: Pakistan vs New Zealand - Highlights & Stats
