transmission, and rear axle upgrades along with some very lively stripes, badges, and interior decals. A bit later in the decade, Yenko began to modify the Chevrolet Vega with spoilers, turbochargers, and design graphics, dubbing it the "Yenko Stinger II". Due to difficulties with United States Environmental Protection Agency certification, he only sold the modified Vega without a turbocharger. Instead, the turbocharger sold separately at the Yenko dealership. In 1972, Yenko stopped selling modified cars and began publishing a performance parts catalog from cosmetic modification to engine modification. One of his notable products was the ZL-1 engine, which he produced under permission from Chevrolet. In 1981, Yenko made his last modification, the Turbo Z Camaro. He added a turbocharger to 350 in³ (5.7 L) engine. In addition to Chevrolet, Yenko dealerships included Porsche, Audi, Fiat, Honda, Subaru and Saab. Death Yenko, along with his three passengers, died in March 1987 while bringing his Cessna 210 in for a landing near Charleston, West Virginia. The landing was hard, causing the aircraft to bounce and Yenko to lose control. It then hit a dirt bank, fell into a ravine and crashed. He was 59 years old.
